My wife and I were visiting Brattleboro on Saturday (from Henniker, NH) and right around noon-time, the most god-awful, absolutely bone-jarring horn started blaring. It lasted for probably one full minute, and was quite scary at first (we were only a few hundred feet away - in the public parking lot - so it was REALLY loud. I can only imagine how small children would have reacted). For all that we knew, something seriously wrong had happened. People driving by seemed as equally alarmed as us.
So, what the heck was that all about? Does it happen every day? I can't imagine living within 5 miles and hearing that every day!
