David Marshall founded Airtight MC (ATMC) over 35 years ago in 1983 at the Marine Lounge in Tulsa, OK. We were a private brotherhood of close friends that rode Harleys together and had previously chose to live the 'Biker Lifestyle' for our entire lives. This club still has three of the original six members ("David's Boys"). We are not a 1% motorcycle club nor are we members of the AMA and there are no LEO's in our club. Never has been and never will be. We "claim" no territory and never will. We are not a support club. In 1991 the club dwindled to only two members. Lloyd Chapin and Larry Hildebrand. Larry brought in his son Khan Hildebrand on his 18th birthday and the club was only three members for the next twenty years.

In 2009 Lloyd Chapin submitted a request to the Oklahoma Confederation of Clubs and was granted that request, (with conditions). More on this in the coming days and weeks.

Our Colors are Black & Grey. Our Brothers have been riding motorcycles 40-60 years. Some of us have have been deer hunting and fishing buddies for over 35 years. We are family men, fathers, grandfathers, and great-grandfathers. We work hard, we play hard, we ride hard, and take care of our Brothers. Priorities are Family, Income, and the Club. In that order. ATMC has a small old school type membership. We respect all clubs and support none. We are independent and choose to mind our own business. We are a private club with only one chapter located in
Green Country and Western Oklahoma.
