I am just wondering if there are any ways to search for providers by general location or city, maybe even a map.

I live North and it is such a pain to drive so far south.  Are there any good providers on the north side of the metro?

... and use a radius of 0 miles.  Then only providers who are linked to that city in TER will show up.  UNLESS there aren't any.  Then the search radius is automatically widened to 200 miles.  And of course, if the provider is linked to Minneapolis or St. Paul even though they work in a suburb, searching by the suburb won't find them.  Also, it's possible the location info in TER for the provider is out of date.

So not perfect, but it might give you some ideas.
