Polar Bear That Killed Student Was Starving I'll refrain from any op-ed about students/universities/professors venturing out into what is actually a very dangerous world where animals don't have supermarkets. Anyway, reading this it occurred to me that "bear flares" might be something useful to check into as another force multiplier. Anyone have any knowledge of them (read: actually used the perimeter defense system) or could offer any alternatives. I know there are seismic detectors and all of that, but I figure a bear alert system would be fairly cheap and uncomplicated...except in this case, where it either didn't work, or they didn't install it correctly. Additionally, having a few boxes of the flares might not be a bad idea just to have around. I have Googled and found plenty of bear bangers/flares, but not a system specifically set up as perimeter security.
