Someone isn’t happy with the neighbors. Residents of 317 Water St. recently put up this sign in their side yard, two doors down from Trafford, the restaurant within the Warren Town Wharf property. It first went up last month, but was added on to this past week with the addition of Blount. One commenter on social media said that as far as Trafford’s goes, the sign painter may have a legitimate gripe: The noise from exhaust and AC fans on the restaurant’s roof can be quite loud, he said. No word on who installed the sign; the house is owned by Riverside resident Carol Connell, and nobody came to the door Thursday when a reporter knocked.
