While fixing connectivity errors using maproulette (its fun btw.) I found the following location in Medicine Hat, CA.
The streets mapped by user Yorii are done very strange (not connected, messed up connection of other roads). IMHO this seems a bit like someone was toying around with an editor (if not I apologize in advance). I can't find these roads on Bing either. It could very well be that they were added after Bing img was taken. It is hard for me to verify this form my armchair in Europe.
Is there newer Imaginary available for this region? Or is anybody living there who could go out and verify their existence?
Thanks and again. Sorry if I make false acquisitions, this is not my intention.
