Here's what was in my car 14 May 2001, as a life snapshot from a vehicular angle, and testimony to my poor clutter management skills. No particular order. What it all looks like (big image for now).

  • Three Allstate proof of insurance document copies
  • California Motorcycle Handbook (2000 edition)
  • California Driver Handbook (2000 edition)

  This note was left on my car with a white paint scratch on my front fender where Author #2 had been a vengeful twat (unbeknownst to him, upon the wrong guy)

• Two sliding tire pressure gauges
• 12V booster cable (don't leave home without one)

• Two APC Smart-UPS (1400VA rackmount, 1400VA 220V under-the-desk)

What have YOU got in your car? :-)
