I've been to Yellowstone three times....and every time we encounter Bison, we encounter people competing for the Darwin Awards.

And not just there, in Yosemite, we were hiking. We started at the crack of dawn, trail begins at 7k feet...goes up another 2k and is just over six miles. Great trail to an alpine lake. Up there for about an hour, then we had to head back down, don't want to hike in the dark.

My brother was ahead of us and ran into a family and they asked how much further is the lake...they were barely a half mile in. So he told them they would not make it as he started in the early morning and is just now returning when its almost sunset. Then he looked at them and said "Where's your gear? And water?". They hold up a small little water bottle. He told them if they continue, he would report it to the rangers as they were risking their lives and those who would have to rescue them. Needless to say, they weren't happy.

After he left them, he radio'd me and told me about the situation and asked me to watch out for them. I eventually encountered them and thankfully they were walking back. Radio'd him back that common sense finally won the day.

I strike up questions from time to time with rangers....good grief. One in Yellowstone got asked a question, "What time do they let the animals out?". I have little hope for humanity.
