If you're around the Kansas City area you should join us at KC Mod Motors. Our link is: https://www.facebook.com/groups/141637099348537/
A lot of the big groups here are too "official" and require things such as fees for membership. This group is just for fun getting together for cruises and pics on good days. This is just a local group of mod motor guys, but with more people I'm sure we can get a good Missouri chapter going.
