Each year on Patriot's Day (the 3rd Monday in April), the Acton Minutemen[5] lead a march from Acton Center to the Old North Bridge in Concord. This route is known as 'The Isaac Davis Trail' and is listed on the National Register of Historic Places. Since 1957, Acton's Troop 1 [2] of the Boy Scouts of America have organized an annual march along the Isaac Davis line of march, and since 1976 the "Scouters of the Isaac Davis Trail" have organized the annual Isaac Davis Camporee [3].
