St. Petersburg -- NYET!!!

I was just recently in St. Petersburg, Russia, where I was robbed on the street of my 24-70 F2.8G lens by two men. I guess I should be very thankful they didn't take my D4 too! This has been devastating both in terms of being robbed and being suddenly bereft of the lens I had taken to do all my holiday photography.

Lens stats: Nikon 24-70 f2.8G ED AF-S US293020

Any suggestions on what and where to post where I can let both Nikon and other people know that this lens is stolen and to not be party to its sale of transfer?

Thanks,

Mike Ross
