Well I'm extremely picky about where I sleep, even when loaded, so these aren't my stories but one of my buddies.
His biggest fear is getting fucked with when he passes out, so the one time when coming home from a bar and couldn't make it home, he climbed a tree and found a comfy spot up in it to pass out.
The second time he walked into someones garage (NO idea whos it was) and slept in the back seat of their Caddilac.
The tree one is my favorite.
