While we traditionally keep our Christmas tree around until well into the middle of January, those who like to start the new year fresh can dump off their used tannenbaums at any one of these locations according to the Sign On San Diego:
Drop-off sites at Calavera Park, 2997 Glasgow Drive; Poinsettia Park, 6600 Hidden Valley Road; Stagecoach Park, 3420 Camino de los Coches; Fire Station No. 1, 1275 Carlsbad Village Drive; and Palomar Transfer Station, 5960 El Camino Real.
