Thanks to all who helped this large, unwieldy TB along, and all of those who followed its travels.
It appears to have disappeared. It hasn't been logged as seen in 1.5 years (Sept 2010), so I think it is gone.
Bicycle had a nice long ride, longer than I expected: 4 years from 2006 to 2010, and 3300 miles. Not bad for a bike ride.
Maybe someone reading this can start their own bicycle TB (or other vehicle?). Who will release the automobile TB? Hmm...maybe a scooter TB is more appropriate.
