Another explanation for food bags being taken by bears?

[Odd Man Out]

An informative post, thanks.
All my backpacking is in Grizzly (and Black Bear) country here in the Greater Yellowstone Ecosystem. My method is to hang food and keep a clean camp, and I doubt I'll ever sleep with food. I've never had a problem, but I also don't backpack inside the National Park where the odds of finding a more habituated bear are probably higher.

Thanks Brad. Re-reading my previous post, I see that I failed to indicate that in the e-mail discussion I referred to, we were specifically discussing east coast US black bears. I should have pointed that out. Clearly, Grizzlies are a whole different story.
