Don't ask me how I know these things, I just do.
1. The guitar of the noisy teenager at the next campsite makes excellent kindling.
2. On a similar note, unpacking your DJ equipment and leaving it in plain sight is helpful in keeping neighbors to a minimum.
3. Bear bells provide an element of safety for hikers in grizzly country. The tricky part is getting them on the actual bears.
I hope that these few words of wisdom have helped you NOT EVER CAMP AGAIN!
