The two states' attorneys general are reaffirming their shared boundary.
State laws require the two to meet every seven years to reaffirm the border. The laws followed a 1935 U.S. Supreme Court decision that settled what had been a bitter dispute.
New Hampshire Attorney General Michael Delaney and Vermont Attorney General William Sorrell fulfilled their responsibility Monday on a bridge over the Connecticut River between Norwich, Vt., and Hanover, N.H.
The two lawyers joked at first about the dispute that started over which state would be able to tax a southern Vermont paper mill. The court ruled in 1935 the boundary is the low-water mark on the Vermont side of the river.
