A short old film clip of Endicott Rock State Park and people watching the boats come in to Lake Winnipesaukee, NH shot around the 1930's or 40's. Maybe someone can actually date this a little better based on the amount of fill around the monument.
Check out the boat going like hell through the Weirs Channel at about 00:35. Shame on those old timers no respect.
