Warning : True Yankee tale and a question for you all.

We had a Selectman here in town who was a non-practicing attorney with a penchant for seeking out odd responsibilities of Boards of Selectmen. He struck gold in 1976 (the USA Bicentennial) and informed the board the NH RSAs (revised statutes annotated) required selectmen to walk the metes and bounds of the town every ten years. The law had been passed in the early days of the republic! Further, he noted that the responsibility had not been met for many years!
Well, duty bound, the Board could not ignore the law ... after reading the requirements the selectmen learned the discharge of the obligation entailed contacting the Boards of Selectmen of all abutting towns to meet at each of the bounds... a minimum of three selectmen from each town at each bound.
The selectmen parceled out the meetings so no one would have the burden of all the meetings.
The town assessor, who keeps the plats and maps dating from the town's founding in 1600s, discovered one of the bounds is in the middle of the extensive salt water marsh!
The state Fish and Game Department was consulted about the advisability of walking the bound over winter ice and were told the salt water ice would not support any weight over that of a bird.
So both the towns had to rent Boston Whaler boats. The date was set for the marsh meeting and of course it was one of that winter's coldest and windiest days!
Bundled up to the ears, wearing heavy boots and encumbered by life vests the selectmen made the meet and discharged their duties and filed all the documentation with the state.
The selectman who had brought up the whole thing was not among the three who had to make the Great Marsh Mete."

the Question : to best of my knowledge the metes and bounds have not been walked since 1976. Should I call the Town Manager or the Chairman of the Board of Selectmen?

Ah, life in small towns. We have to take our amusements where we find them!
