Went tent camping there with some pals long ago. Nice prairie dog town there. Buffalo run free. Had a nice campfire and next morning, I am quietly awakened by a gruff noise. I look out my tent and there in the other tent, a buffalo had its head inside the tent. I grabbed my camera and took one snapshot, then laid back down until others got up. I said nothing, but a week later, I gave all the other guys a copy. They were disbelievers at first, but the reality hit them all at last. Best laugh ever.
