If I were trying to get the free spot, I would say that its extremely manly to step outside your tent after a great drunken evening and come to each of your tents to take a wizz outside each of your doors with a pleasurable grunt each time. Along with that comes an awesome fart that follows each trickle.
But then, I am not competing for the free spot because I live so close that i will be enjoying my own bed and pissing in my own bowl :D
