Late summer of 2019 Upstate NY just north of the town of Nassau. On the Kinderhook Creek

This encounter (if that's what it was) was incredibly brief and to be honest may be absolutely nothing. Although it did strike me as quite curious. I wouldn't say that I'm an official "backwoods redneck"(a term i use with loving endearment) but i have grown up in or in the vicinity of wooded areas my whole life and spent a handful of years as a boyscout(troop 277 baby!) as well as just generally running around the woods at an adolescent/young teen age and younger. Making forts, climbing ANYTHING accessible and lighting the occasional slightly"controlled" burns, as well as general exploration and observation of "the world of woodland creatures" were the main activities we engaged in. Thusly i believe i have a good basic knowledge of the local flora and fauna and the general behaviors surrounding them. This particular occurrence happened at around 2:30-3:30 a.m. and was witnessed by myself alone. I have two children and since i grew up camping and some of the greatest childhood memories i have involved camping and being in the woods i have always aspired to obtain a camp of my own in order to create some valuable and lasting memories for my children in that respect. Well the summer of 2018 presented me with an opportunity as a friend's mother was selling her old camper at a price realistic enough for me and the following summer i was proudly stationed at lot 34 in Kinyon's Canyon Campground. This particular evening(it was around late July early August i believe) i was at my camp with my two children, their beautiful mother, and another friend with his two children and girlfriend. It was growing quite late and everyone else had passed into the realm of dreams following an eventful day filled with water activities and exploring the campground ending with hot dogs and s'mores aplenty. I enjoy the solitude and silence the late hour provides and so was taking advantage of the opportunity to stare into the flames as i mulled over life and it's meaning. After a while i grew restless and decided that a moonlit walk was needed to clear my head and invigorate my soul. I started in the campground and walked the main road leading out to old 66 i believe. Upon reaching the main paved two-lane road i took a right out of the campground and walked straight down the middle of the double yellow lines as i had checked my phone before i left and it was 2:38 a.m. i intentionally left my phone as i was craving as secluded and unplugged an experience as possible. On my walk down the road i didn't experience anything out of the ordinary and things were uneventful as i silently strode down the lonely stretch of back road. This area is quite heavily wooded and while the general wooded terrain wasn't impassable were one to go "off the beaten path" the trees were thick enough to make a veritable canopy over the road and with few street lights along the way it provided a generally pitch black environment in which seeing your hand extended in front of your face was an unlikely scenario. I walked for, if i had to guess, around a half a mile down the road before i encountered a large fenced in compound on the lefthand side of the road. I noticed the sign read Tennessee Gaspipeline Company or something to that effect, something which struck me as funny being that i was actually born in TN. Severeville if anyone is interested. It's near Gatlinburg in the north-eastern part of the state. At any rate, after exploring the immediate area visually for a while(not much couple of large industrial looking buildings in front sprawling out into a larger compound that was mostly shielded by said buildings) i followed what appeared to be the start of a path into the woods across the street from the compound. It looked as though the company owned the land on this side of the street as well as upon entering the "trail" i observed a chainlink fence topped with the quintessential three rows of barbed wire that mirrored the fence on the compound side. The side i was entering into was the side that the Kinderhook Creek ran on as well as the side the camp was located on(the Kinderhook runs through the back end of the campground and is approximately 2-300 yards from my camper as it's located in the campground). What i thought was a trail ended up going off the road mo more than 100 yards or so and ended in a large approximately 40 foot diameter circle that was cleared and mowed and maintained. At the edge of the treeline somewhere near the middle of the circle a large 8-9inch diameter pipe came out of the ground. Not sure what it was for but i decided to relieve myself somewhere next to it and as i did i heard a loud kind of clattering noise out by the road to my right and behind me a bit. It was very distinct and very noticeable as it was around 3 a.m. at this point and there was no one else walking around to my knowledge. The noise of the creek could be heard through the woods a short distance away but it wasn't sufficient enough to drown out noise in my immediate area. I definitely heard something. I was slightly distracted with my thoughts so it didn't really register until i made my way back out to the road and shined my brand new flashlight bought specifically for this trip absent mindedly over to where i heard the noise. As i stood there observing a whole lot of nothing but trees and bushes it dawned on me. That noise i heard was the unmistakable sound of someone/something launching itself up and over the fence. The 8 foot tall fence. With a row of barbed wire that topped it adding at least another 2 feet to the overall height. I've personally, in various situations, launched MYSELF over seemingly innumerable chainlink fences to the point that the "sprooong, whack whack"! sound of a clean, single bound over one is ingrained into my memory of sound profiles. While this realization dawned on me(slooowly, more slowly than i care to admit) i decided that it was time to make my way back to camp. All along the walk i kept periodically casting the beam of light from my flashlight over into the woods on my left(the side of the road on which the sound was heard). Although i didn't see anything i couldn't shake the feeling of a "presence" out there observing me. I may just have been spooked and working myself up though because the more i thought about it the more i became convinced that what i heard was something grabbing the top of at least a 9 foot tall fence and casually hopping it's way over it in one clean motion. At three in the morning. In the middle of the woods. The walk back was equally uneventful and i made it back without further incident. Everyone was still asleep, and i was soon there myself. Like i said, it could be nothing, but if the noise i heard is what i think it is...that leaves some questions to be answered i believe. As far as i know, there are no KNOWN animals that could accomplish such a task in MY area. Anyway, thank you for listening, i hope it's at least somewhat intriguing. Also just a quick mention, while I'm not aware of the prevalence of bigfoot sightings in the immediate area it is about an hour south of the Adirondack mountains and an equal distance south east of Whitehall, N.Y. both areas with a history of sightings and activity. Hope you enjoyed the story, and God bless.
