there was a news report of Grizzly bear attack on female mountain biker who was jogging with a friend in British columbia, Canada. She was stalked over a mile. She climbed a tree but the bear still drag her down. I think that it is best to carry bear repellent spray when one goes into bear country whether you jog or bike. People are building their homes into bear territory now. The bear lose its fear of humans. Once it happened tradgedy always follows.

Do you guys carry some sort of sharp folder to defend yourself in case of black bear or mountain lion attack ?
