Here's a notice from the town of Hamden:

Hamden—Hamden Public Works will begin curbside pick up of Christmas trees on Tuesday, January 18, 2010.  Trees should be free of all wrappings, lights and decorations.  Artificial trees are not included in this pickup and may be disposed of during the bulk trash months of April and October.  Pick up will be town-wide and continue through the end of the month.   Residents may also take their discarded trees to the Transfer Station at 231 Wintergreen Ave (open Mon. - Fri., 8am-3pm).  Please contact the Help Desk at 287-7676 with any further questions.

And by the way, Mayor Scott Jackson wishes to thank the McMahon family for donating the Christmas Tree located at Freedom Park at Whitney and Dixwell avenues.
