Bloomington is convenient for the traveling provider, because that's where the airport is, and MOA, of course, which is on most people's bucket list.  I still cannot figure out why some of the local hobbyists dislike going to Bloomington; I can only assume they live in the north area of the metro and don't want to waste gas.  But even though downtown Minneapolis might be closer, there's still the parking to pay for.  So I vote Bloomington...or any location near a major highway.
