<P> In the 1979 novel Alongside Night, an organization called the Revolutionary Agorist Cadre, seeking a Second American Revolution, welcomes visitors to one of its undergrounds: "The room's only decoration was a modified Gadsden flag draped on the wall adjoining the bar and medical areas (opposite the door), a golden field with' LAISSEZ - FAIRE!' in an upper left corner, a coiled rattlesnake facing left with its tongue out, and in the lower right,' DONT TREAD ON ME!"' The Gadsden flag without the addition of "LAISSEZ - FAIRE!" is carried over into the 2014 Alongside Night movie adaptation in which the Gadsden flag is used by the Revolutionary Agorist Cadre as well as the traditional anarchist black flag . </P> <P> In 1970, on a verse from song Uncle John's Band by Grateful Dead contains "Their wall are built of cannonballs, their motto is' Don't tread on me"'. </P>

Where does the saying don't tread on me come from
