The problem in your thinking Dan is you are assuming that location plays no role in how frequently some people show up. I'm honestly not a huge fan of Porky's food, and I can't have a beer there, AND it's a hell of a drive for me. Move that wednesday meet somewhere up north (equally far away from minneapolis as apple valley or eagan is if thats what your thinking) and to someplace that serves decent food and beer, and see how much more frequently I show up.
I can't promise the same will hold true for other members, but just assuming the reason the 'regular' crew is who it is, has nothing to do with location, is probably not real accurate.
I think thats why moving it around the city to 3,4, 5 different places makes a lot of sense, not everyone is going to drive to all of them but it'll get a lot more people out (IMO). Also moving it to once or twice a month might also help how many people show up. If it's EVERY week it's easy to just pass it off but if it's only once a month people may feel more inclined to show.
