Everyone who argues with a bear loses. My dad took me hunting once and we saw a bear. He pulled out his 357 and we slowly moved back to the car. My dad was sweating in rivers. Told me to be sure and save one bullet for myself if it ever came down to it with a bear. Dad was 6'2" tall and weighed nearly 300 pounds. Scared me to death.

I heard some wierd noised during the night and the next morning an F-150 a few yards away had the drivers side door peeled open like a grape. There's a reason they say, "Don't store food in your car!"
