Level 1: Iphone, wallet, keys w/ a small led flashilight. Keep it all to a bare minimum. Wedding ring left at home today, oops.
Level 2: There's some stuff in my glove box, but the handle broke so current contents are unknown. Can't be important, though - spare business cards, pens, etc.
Level 3: Car trunk has some pens, assorted field measuring gear, CD's, the game discs for Diablo 2 I had loaned someone last year, a blanket, and assorted junk. Last time I opened the trunk something inside grunted what I think was "hello," so I don't go in there any more.
