I too have been fortunate to not have ever had a bike stolen from me. Came close when I was a little kid though. I parked my stingray in front of the candy store where two "big" kids were sitting. They were still there when I came out a few minutes later, but my bike was gone. Something made me look behind the small store, and there my bike was! I jumped on and got the heck outta there as quickly as I could! Learned myself a lesson that day.
