Bears

I have searched as best I can to find out how TM perform in bear country. I'm either not knowing where to look or it hasn't been asked.

In Grizzly country, they have bear lockers for food storage. I've seen what the state parks show when people leave a candy bar in the car and bears tear in. I just have visions of being wakened from a sound sleep with a bear clawing in because it smells food through the gaps with Velcro or the slide for the bed.

What has been real experience with this?
