I was hiking with my 2 dogs behind Castle in the Clouds last year and I definitely felt something watching us for about 2 minutes. The hair on the back of my neck suddenly stood up and I felt very uncomfortable.
I can't explain it better than that, but it was the first, last, and only time I've ever felt like that on a hike.
I never once thought of Big Foot (my first thought was a mountain lion, especially when we had turned our backs on the area I felt we were being watched from).
The fact that my pups didn't smell or notice anything eased my mind a little bit (they can spot or smell a deer minutes before I can know there are any in the area). But it was a very eerie feeling. I didn't like it in the least. It passed quickly though and I've since told a half dozen people about it.
I always wanted to believe in Big Foot as a kid (what 12 year old summering in NH doesn't) but who knows. I catch myself watching the Discovery channel any time a Sasquatch documentary comes on.
The one thing that sticks in my mind is when a scientist said people very rarely find bear carcasses and they're a lot more prevalent than "Big Foot".
Which can dispel the argument of, "Why doesn't anyone ever find a dead one?"
This thread should definitely take some interesting turns.
Looking forward to it.
