Sometime in the 90s I tried to remember bear encounters, and came up with around 60. There are probably another 30 or so that have left the memory bank. Only 2 or 3 could be construed as possible attackers. Many more were habituated to humans, and tough to deal with.

Really great reading is the book by the Craighead brothers that invented radio collar tracking in Yellowstone and did the first comprehensive studies on grizzlies in the Greater Yellowstone Ecosystem. "Night of the Grizzly". They were drummed out of the corps by the NPS for being too independent in their thinking.

Does any one remeber the days when the bears lined up on the road in Yellowstone and walked past the tent all night? Or how about waiting for the tram in Yosemite in the 70s and seeing 5 bears walk by? I did a job for the NPS once in Yosemite and stayed at Curry Cabins. There was a bear in the unlocked dumpster every morning on the way to breakfast.
