Bear Food

My husband and I were discussing backpacking the other day. I was asking about bears.
He told me that if you ever encounter a bear you should either lay down in the fetal position and not move OR try to make yourself look bigger by raising your hands and lifting your backpack over your head.

Look, I don't know about you, but if I'm hungry and I see a hamburger I'm going to try to eat it. Especially if it was running and now it stops. Bonus if it can make itself bigger.

This sounds to me like Bear Propaganda. They might have a man on the outside. Smoky perhaps?
