Balloons, Double X tree leans, and a "Pssst" in Sam Houston Forest

Paranormal Shaun posted a video of a hike they did in Sam Houston Forest. It's about 40 minutes long and it's more or less a walkabout video BUT two interesting things happened. At 4:45 they came across a bundle of balloons that were just hanging out there in the forest, which is of interest if you follow the theory that this is an indication of Bigfoot. At the 16:13 mark they come across double X tree leans and at that point there is a "Pssst" sound. It could just be a quick snake hiss but it is interesting that it happened at this location. Take a look here:
