Sorry guys I have been fishing for the last week.
My sighting, well I can genuinely say was one of the most deep down fears I have ever felt.
Anyway this happened way back in the early 90's along the Snake River in Eastern Idaho. It was August during a full moon. My friend just bought a new shotgun so I know it was before September 1. I can not recall why we were there, we were not drinking as usually occurs when friends gathered back in those days. My best friend and his brother where with me as well as a group of girls that always hung around with us.
A loud constant chirping whistle arose back behind the archery range. One of the girls asked what it was and of course we decided to find out.
That night the moon was bright, we did not have a flashlight nor did we need one. The open spaces between the cottonwoods were plainly visible. The remnants of the old gravel covered roads with the light colored river gravel seemed to shine white and were easily followed.
The whistling sound seemed to stay the same distance in front of us until we reached the levy that redirected the river channel. The white gravel on this road was really white now that the trees were behind us and there were no shadows. This levy is quite a bit higher than the surrounding brush chocked land and as soon as we were atop of it the whistling increased from several sources.
There was one girl out ahead of our group 20 feet or so who had a arguement with one of her friends. As we started down that road a shape shifted position under a patch of wild daisy's in the center of the road about 60 yards ahead. My first thought was a beaver as it was low to the ground and dark colored. I told my friend that the girl in front was about to get the crap scared out of her when she walked up on that beaver. We were now within 40 feet of that weed patch when it stood up and all hell broke loose with the whistling below us in the brush. It first tried to go towards the brush then turned 180° and ran then JUMPED into the river.
That first girl was almost on top of it and was the first back to the vehicles locked inside. The worst part was knowing we had to go down that road with whatever was whistling along side of us. We all ran out of there with no further problems and drove the hell out of there.
I can definitely say it had fingers, it was on two legs, it had tufts of hair on its elbows longer than the body hair, it was very fast and had a movement that just was not human to it. The arms were longer than the legs, almost mid thigh. This was a young adolescent about the height of my 13 year old kid. It plainly had the shape associated with the bigfoot and was no escaped ape as it plainly swam the river.
Anyhow that is what I saw and still see when I think about it. I dont like the dark anymore, i bought a game camera to keep them away from camp and when I hear that chirp come from the forest I usually move. These things are nothing to mess around with. They scare you to your soul.
