I don't know if its has been posted elsewhere, but Ton Madak's light show is up and running in Calumet Grove. A can't miss, even with Santa on some nights!
He has posted a video of one of the "acts" at
www.vimeo.com/54625266.
There are also links to his shows from the past few years.
It is best to go by cart and take a couple of folding chairs so you can watch the whole show in comfort.
Hats off to an amazing guy and all his tolerant neighbors.
