In a day and age when most marriages don’t last 25 years, Sam and Ann Douglass achieved that milestone long ago and accomplished another one: 25 years as business partners as owners of five Discovery Map franchises. The couple recently celebrated their quarter century in business together with the following Discovery Map locations: the Lakes Region/Winnipesaukee, Hampton Beach, Kennebunkport/Wells, York/Ogunquit and Camden/Rockland.
