Late to the game here, but here's my take on it all.
Yeah, searching for sasquatch still has my interest.
HOWEVER.
There are so many other things that I love to do in the woods. I love camping and day hiking. I love fishing and fly fishing. I love mushroom hunting. I would like to take up hunting - grouse specifically - in the near future. I'm beginning to take up backpacking and looking into multi-day trips. I want to try horse-packing trips somewhere pretty. I'd like to campfire cook better, and learn to dehydrate and create backpacking food.
That said, there are MANY other reasons to be out in the woods than pure bigfoot or cryptid hunting. Our trips are always dual or multi-purpose adventures. I'll never get bored of it.
As far as books or movies or even videos - well, there's some people I really enjoy watching (Joe and Jessi @ Hellbent Holler for one, but most I can pass by. I'd rather be out there doing it myself (and doing it better tbh) than watching other nerds in the woods
@BobbyO, I completely respect what you're doing and wish you all the best!
