When we (my parents and I, I was in my teens, this would have been back in the late 60s) were there (Glacier park) it was the year a couple college students got killed by a Grizzly bear. Their campsite was 1/4 mile from ours. And that night some folks in a tent ran a big bear off that was trying to get into their tent (we were in a camper).

IF I remember correctly, and I could very well be wrong one of the girls was, well, you know, that monthly thing. Plus they had some candy in the tent with them.
