The Super Mark Twain membership level is a family membership. Family membership includes all immediate family members living at the same street address. Membership in HFFC gives you access to all of our events. First time members at this level are entitled to the special gifts of an HFFC T-shirt or tote bag. With membership, you help all of us maintain a secular community in Fairfield County. Memberships are for the calendar year. Members joining after October 1 will have membership extended through December 31 of the following year.
