Getting close to camping trip #400 in my lifetime. My Dad was never without a gun while camping when I was a kid and I always have one while out with my family or friends.
Only times I've been without one was while camping with the Scouts with my Son, at camps that were more like Disneyland than real campgrounds.
I have tents but like to bed down in a vehicle whenever possible. About ten years ago two buddies and I were camping in the Southern Sierras on a quail hunt. I was sleeping in the back of my Ford Explorer, they were in tents. At dawn, one of my buddies excitedly wakes me up to tell me there's a bear ~100 yds away. I look out the window and say...
"Yep, that's a bear. Wake me up at 7:00..... or when you run out of ammo."
