Two fireworks launched into its top gave the signal to light up the 90-foot-tall blue spruce. Rice Park was home to the annual tree-lighting ceremony that included 30,000 holiday bulbs. There is an interesting note about the tree’s height at the end of the story. Also opening that night was the WellsFargo Winterskate ice rink. In case you missed it, the lights and the ice rink will run through January 1.
