Yeah, I'm not surprised.
I've started to worry a little bit more about theft. It has always been something I take seriously, having had one car and one motorcycle ripped off during my vehicle owning career. I park my Prius now only in a secure parking garage AND club the steering wheel on work days in Philadelphia. On weekends I park the Prius in at the end of the drive and switch over to my old pick-em-up (pinch hitter for the Prius for local short trips). Oh yeah, the old truck now has locking gas caps on its twin tanks; 38 gallons of gasoline, or over $150.00 worth at todays prices.
