Perambulation of the town borders is a traditional duty of town boards of selectmen in the American states of Massachusetts, New Hampshire, Maine (certain towns), and Connecticut (certain towns). In February 2020, the Portland Press Herald reported that "Maine law used to require neighboring towns to perambulate, or walk their boundaries, every 10 years. In the last century that practice became rare, and in the 1980s, the requirement was taken off the books," according to Robert Yarumian, "a professional land surveyor and owner of Maine Boundary Consultants in Buxton".
