Okay, I wasn't going to respond to this, but after reading the other posts, I changed my mind. I will say that I DO NOT believe in UFO's with beings from other planets, but I DO believe in Bigfoot, and always have. Have never heard or seen anything that makes me believe, but have a couple of friends and two brothers who have.
My brothers and a friend were going on a three day hike. They got a late start, and were not able to make it to the place where they had intended to camp. So they found a spot along a creek, in the dark that seemed like a good area to camp. They got a fire going, tents pitched, etc. 30 mins. later while sitting around the fire talking, something starts screaming at them from just outside the firelight. My brothers said that it was obviously screaming at them, and was so loud and close that you could FEEL the screams in your chest. A very loud, raspy "woo, woo, woo". They all looked at each other, and when it stopped my youngest brother asked my other brother "what makes that sound?", and then it started again. After round two, they were all sitting with their backs to the fire with knives and one machete for defense, but never heard or saw anything else. The said that that it was a very restless night, but the rest of their trip was uneventful.
I have some other stories from friends, but this one is as near to a personal experience as I have. Scott
