It’s a terrible idea to close the Old Mill public space! For better or worse, we can’t control how far sound travels and it is not fair to restrict access to a public or private non-related venue because of errant “free” sound waves, i.e., those the producer is logistically unable to charge for.
Where would this stop? Would they not allow homeowners to go out onto their decks and patios so they wouldn’t hear the sound free of charge? Ridiculous. Maybe they should just turn it down!
