It's 2 a.m. Something heavy is circling your tent, sniffing the nylon a few feet from your head. And then it just... leaves. Why?
Every summer, huge numbers of people sleep in bear country, yet bears almost never drag anyone out of a tent. In this video we break down the real reasons: a grizzly can eat 40,000 moths in a day, a bear's nose is about 2,100 times better than yours, only about 12% of fatal black bear attacks happen between midnight and 6 a.m., and the rules written after 1967's Night of the Grizzlies changed campgrounds forever. We also cover bluff charges, why black bears and grizzlies need opposite responses, Yosemite's minivan-raiding bears, the rare predatory attacks, and what to do if a bear ever comes into your tent.
