For the purpose of M & G and other events it doesn't matter which chapter you belong to. Any member can be a member of any chapter except for the formation of a new chapter if I interpret the bylaws correctly, ie the KY OH IN MI chapter gets started and if someone from IL wants to be a member then they can. The stickup would be the person from IL cannot be one of the 15 members counted towards the forming of the chapter since he's not in the geographical region for the forming of the new chapter.
Looking at a map, IN OH KY LP of MI seems to be small enough to have local events and should be large enough to have 15 members who could want to have a more local chapter. I'd suggest posting a new thread in the main members forum seeking a show of hands for members who are in that area willing to form a new chapter. If you want help with working on what problems you may have forming the chapter, try asking the AZ chapter what hurdles they had to get over. They tried several times to get a chapter before it actually went through.
