Traci at the Northside Neighborhood Watch just forwarded on a valuable link; http://www.stolenbicycleregistry.com/
This website will track stolen bicycles in an area. As we have periodic spikes of bicycle thefts in our area, I encourage you to make use of this site. Also, if you have a bike stolen, I encourage you to list the serial number on this site. Perhaps it will help you get your bike back!
