What do you get for the person who has everything this holiday season? How about a municipal street sign-you know, the real McCoy, straight from the city of Woonsocket. And it's all for a good cause, says Mayor Lisa Baldelli-Hunt: The Milk Fund. "These signs will make a great gift of decoration for anyone's home, office, or place of business, and the proceeds will help a very worthy charity,"the mayor said. The city will be selling the old green-and-white signs for $10 each.They're available because the city is in the process of replacing them. A complete list of available street names will be posted on the city's website, www.ci.woonsocket.ri.us. The signs will be available for sale in Harris Hall, inside City Hall, through Dec. 31st from 9 a.m. to 3 p.m. City Hall will be closed Dec.24 and 25.
