That would put an end to mail in registration renewals and force everyone to travel to the town hall in NH in which their boat is registered. Another anti-tourism move if you ask me. Just look at the pole asking how far away from the lake that people live. 70% of the people responding live over 50 miles from the lake, most of them obviously from out of state.
Now, that said, what has that got to do with a FREE sticker to identify the owner of an unregistered boat that, if adrift, would spark a search for a missing person?
