Go backpacking in Yosemite.
Better have your food up in a tree once the sun sets.
A bear licked my brothers face once while he slept, yikes!
I once took a raft ride in Yosemite. As we floated along, there were people napping/tanning by the river. A bear walked out right between 2 people to get a drink. It drank, and then walked back into the forest. The people never even knew. We on the raft remained silent to not spook the bear, literally 1-2 feet from 2 people.
