Locate a safe, clean source of water. You can live for days without food, but not very long without water. However, if I am the only one left, would I really want to hang around?
Raid every store I can think about. I won't be here very long. I bet it stinks though.
@Sheannutt It would stink everywhere there was a human corpse.
go to the DMV and walk directly up to the counter, drive around in a badass car looking for badasser ones, brush up on my bowling skills, throw things from really tall buildings just to watch them smash, go to all the Posh hotels and stay in a different bed every night... one thats made up of course.
