My new bike - tee hee hee

[Rosie8]

Could have been dumped or stolen. If you don't want it, advertise, donate to Salvation Army or Christmas bike programs (where bike people fix up bikes for poor kids), etc. It's very strange what people will abandon out in the country. Usually it's kittens.

Possibly dumped or stolen. Maybe dumped because the tyre looks like it's come off the stabiliser? Maybe worth a phonecall to the local police to see if someone's reported it missing? Could be some little girl's missing her bike.
