The Cookie Monster was there, so were Angry Birds, beautiful floats, area high school marching bands, and Santa Claus, who arrived via helicopter.   The annual Children's Holiday Parade is the biggest in the state, and it kicked off at 12:30 on Saturday at Kennedy Park and followed South Main Street to Government Center.  The light snow and drizzle did not keep thousands from lining the street to experience the festive event.   Check out our photo gallery.
