Perhaps the breakup should be as follows:
GREAT LAKES: OH, IN, MI, IL, WI
UPPER MIDWEST: MN, ND, SD, NE, IA
HEARTLAND: MO, KS, OK, AR
(TN, KY as a potential 4th or included in Heartland?)
Having a greater number of chapters allows

to better provide a variety of national events with more groups of dedicated locals available to plan outings to many more locations. Personally, being as centrally located in STL as I was in NJ, I would easily travel several hours in any direction to attend.
