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.
