Over the years have talked to old timers that have seen things that couldn’t be explained and were reluctant to talk about them and had nothing to gain by lying.
This is the experience of many people. There are far too many credible people - experienced hunters, game wardens, police and generally well seasoned backcountry outdoorsmen thst have seen something thru could not explain. But you open yourself to ridicule. So why bother trying ?
My good friend Steve has a YouTube channel howtohunt. He discusses this often and has a couple of books about different individuals experiences. It’s worth checking out if the topic is of interest to anyone on this thread.
