That reminds me of a camp we stayed at near the California Nevada border (Bootleg Camp). There were a lot of signs about securing food from the bears. I asked the camp host how bad the problem was and he said no one had reported seeing a bear there in something like the last 15 years. We hung our food anyway, but more because we figured raccoon might be a problem
Campground hosts may not be entirely reliable, reference our stay at Newhalem, WA. Bear signs, but no bear boxes, and we didn't have rope to hang food. So I asked the host if there was some place we could store our (depeleted) food, and he told me, don't worry about it, they haven't had a bear in the campground for 10-15 years. So we left panniers on bikes overnight and didn't worry -- until we got back to civilization, and in contact with my wife. She'd been cruising various journals, and somebody had taken a picture of a bear walking through that same campground a week earlier. At least he didn't bother our stuff!
This may be one of those motorist/non-motorist split kind of things. The bears hadn't started to break into campers, cars, or even locked motorcycle boxes, so the host may have honestly thought there was no problem. And if most of the few nutcases riding bicycles or hiking hung their flimsy nylon bags containing food, maybe there really wasn't.
Or maybe the bear was just picky, and didn't care for instant oatmeal, Poptarts, and Clif bars. "Where's the Kentucky Fried Chicken?" he growled.
