Sorry about your bike. Please post a listing here:
It will be indexed by google in minutes, allow others to contact you quickly in a potential sighting, and also allow other cyclists to learn from your misfortune and maybe avoid the same fate.
Sara, sorry to hear about this.
1 - it wasn't your fault.
2 - I hope you filed a police report, in case you or someone else tries to recover it, it will be a useful record.
