Let's say I live in the Ramsey county area, which is located in the state Minnesota, and started a community forum website for it (eg: ramseycountyforum.com). Would there be any legal issue for it at all?
I would say best thing to do is talk with a lawyer (just to be safe) or go on county website and look into it.
There would be no legal issue anymore than there is one when Orange County Choppers uses "Orange County" in its business name.
