Yosemite Forum

Apparently, they have spotted signs of bears on top of Half Dome. I assume scat or something.

I bet they are sneaking past the ranger checking permits, too.

Bears are exempt from backpacking permits. They aer part of the park service's enforcement team, providing valuable insight into food storage in the backcountry!
