The Highway Barn saga continues

So, since the Highway Barn borrowing failed at Town Meeting, I thought the Highway Barn debt exclusion was meaningless and wouldn’t pass, and then people at the polls were urging people to vote for it, and it passed, although only by 44 votes.

And thus today’s Telegram & Gazette reports they’re considering trying another Special Town Meeting.

The main thing I wonder is how long the debt exclusion is valid for. If this doesn’t pass at Town Meeting again and all is forgotten, can Charlton in 10, 50, or 100 years exclude from Prop. 2½ borrowing for a new highway facility? I tried reading through the law but didn’t see it.
