"Only place is beach of Olympic Peninsula, and it's really just for raccoons"
I guess a raccoon is just a mini-bear, but with opposable thumbs. Raccoons don't have tremendous strength like a black bear, and they don't have much strength in their bite. OTOH, raccoons are much better climbers than bears, so they could get into a hung bag easily.
"Some day I may do something on JMT, are there super intelligent bears there?"
Yes, especially in a few places. Yosemite Valley has a bear problem, but those are mostly bears that break into cars by a variety of methods. Rae Lakes has a bear problem. The Mount Whitney Trail has a bear problem. Maybe a couple of other places. You can tell by where bear canisters are required by the authorities. There are maps.
"Oh, and I use it in my car to keep mice out of food"
One would want to know how the rodents are getting into your car in the first place. Do they use the wireless entry system?
I will comment that the double-latch BearVaults are pretty good. If I foul up and get olive oil on my hands, it takes me about a half hour to get the damned thing open.
