I'm really sorry to hear about your bikes.. There's a gentleman on Bikejournal who had a nice roadie stolen a while back and he's from Alberta, Canada. He never thought he'd see it again. Strangely he DID get the bike back and if I remember correctly (some of the gals on both forums can correct me if I'm wrong) it actually showed up at the Police Dept left outdoor of the precinct I believe.

Years ago my son had a bike stolen, he had left it on the front porch of our apartment for 2 minutes (if that) and went straight back outside and it was missing. We walked around the apartment complex and found it. I had someone go call 911 while I stood watching the bike then they came back while I went to get the paperwork with the serial number etc on it while we waited for the sherriff. The person who stole it had already broken pieces OFF the bike in the few minutes they had it (trying to make it look different I'm guessing) and had hidden it behind several other bikes on their back patio (probably also stolen) When the police arrived, I showed them my paperwork proving that I owned the bike and the thief had the nerve to try to say 1st that I'd broken into their apt to take the bike in the first place, then that when I showed the paperwork with the serial number to the sherriff they had the nerve to say I broke into their apartment to get the paperwork WTF???? They were people who unfortunately had been caught stealing other items in the neighborhood and that was why I wasn't surprised to see it hidden on their back porch, but when I wanted to press charges when they'd literally been caught red handed with a stolen bike the police officer told me lady, just be happy you got the bike back. Whatever, we did get the bike back but it was damaged and I think we ended up having to get another bike eventually but, sometimes you get it back sometimes not and even when you catch the thief in a bold faced lie, it doesn't mean the police are going to do anything about it.
