The Outlets’ annual tree lighting, free and open to the public. The concert starts at 4 pm with the Eric Golden Band, honky-tonk country, and Spinphony, a string quartet; then Santa arrives, escorted by the Castle Rock Fire Department, the Douglas County and Castle View high school marching bands and the Castle View winter guard, to light what the Outlets call Colorado’s tallest Christmas tree, and a drone show follows. Beer and wine are sold for the Humane Society of the South Platte Valley.
