Somebody tried to steal my passenger backrest tonight while my bike was parked for about 2 hrs in a busy parking lot. I planned to ride my bike down to Fargo this weekend, but now I think I'll just drive the heavy-chevy because of lack of security on the bike.

Anybody have any good suggestions for a security system with proximity sensors? - something that would keep people from touching the bike, the handlebar lock makes it pretty hard to steal and most security systems protect against hotwiring, etc.

Thanks
