What's in your "Bad day bag?"

In my truck I carry

long pants (i wear shorts almost all the time)
socks
shoes
t shirt
sweater
blanket
pillow
and a hat.

But since reading this thread I think I'll be adding condoms to the list as I'll be single again very soon. :)

There is also a cooler usually with ice and gatorade in it. Anything else and I'm calling a wrecker or the police.
