Every year, the Friday after Thanksgiving brings Main Street in Old Littleton alive. The yearly tradition starts when the sun sets and has Santa rides down main street on the Littleton fire engine, as the street is lit up block by block. Everyone follows behind with lit candles. It's a lot of fun and has a more "small town" feeling than the downtown Denver holiday lighting.
My family and I were there this year, had hot coco, and took a few pictures. Please excuse the photo quality. I took them myself which explains why I hire a professional photographer to take photos and virtual tours of all of our listings ;)
As a Littleton native, I can remember driving through Old Littleton several times each year just to drive down the lit up street. If you're anywhere near Littleton this Christmas season, drive a little out of your way to drive down the main street. It's worth it.
