Mark your calendars, Twin Citians. The Powderhorn Park Art Sled Rally is January 28. If you've never been, you're missing out. It's a Happy Mutant-filled fun fest of creatively themed homemade sleds careening down a steep hill, ridden by costumed characters. It's also the perfect way to cure some depth-of-winter blues. Check out the video to see, among other things, a sled shaped like a 20-sided die.

I'll be joining BoingBoing readers for a meetup before this year's rally. Hopefully, you can come! We'll meet at 1:00. Reader Emily Lloyd has graciously volunteered her home, across the street from Powderhorn Park, for the meetup location. Bring what you'd like to drink. Bring a snack to share. At 2:00 or so, we'll walk to the park to watch the sledding. More details are on the BoingBoing Meetup page. See you there!
