At Denali National Park, we saw this warning sign and what to do in the event of wildlife encounter. We been to like Yellowstone NP were they always warn people of getting too close to Bison and to stay as far as possible. Here in Denali, it's the warning against Bear, Moose and Wolves. Wolves? that's a scary one, I mean bear is scary too but you hear about bear encounter much more than wolves. I don't know how tough I can be if I see a wolf but let's hope that never happen. I also don't know about out running a moose too but for sure I will be keeping my distance.
