To what do you cling as the last vestiges of your sanity evaporate?

I wander around burnt out crack houses and photograph the things that have been left behind. It's very other worldly, disturbing and haunting. Reminds me that things really aren't so bad, and that I'm really not nearly as crazy as my feelings would indicate. A buddy of mine inspects them for a living; he's armed and good company ~ so I get to kill a few birds with one stone.
