Dating back to 1967, the Zilker Tree lighting has been a tradition for families across the city, and it takes place this Sunday (Dec. 1). Of course, if you can't make it, the tree will be less ceremoniously lit every night until December 31. This year the tree is 155 feet tall and will have 39 streamers suspending 3,390 multicolored lights. Quite a sight to behold, indeed! Don't forget The Tail Of Lights is back this year too, running from December 8th - 22nd.
