1974 Loss #1: Classic black 3-speed Raleigh left unlocked overnight in a fenced backyard. Yet to be forgiven
1994 Loss #2: Costco mountain bike left in an unlocked garage; nothing else of value was missing
2005 Loss #3: New REI urban bike From UW campus mid-afternoon, just a flimsy cable (but I was only gone for 30 min)
2011 Loss #4: Another Costco bike from a parking garage during an overnight shift; it was okay at 6pm; gone by 8am, thick cable and new helmet left dangling on the stand. Chastised by my daughter who had given me a U-lock after #3.
Okay, I'll use a U-lock, and during night shifts, will bring it inside.
