That northbound end section on Damen always get wickedly ice over. Definitely use caution Chicago bike folks
I would advise against attempting to go skating down the bike lane on the South Damen underpass if you want to retain your teeth this winter

Terrifying: A kid on a bike was reportedly sideswiped by a semi-trucker yesterday during the rush at 35th/Archer in the 12th Ward, just NE of the Archer traffic safety project area. His bike is trashed. Protected lanes can help prevent this kind of crash.

Was a great opening 👍🏻
Last Saturday we rode to the opening party for the 28th annual Bike Winter Art Show, and checked out some sustainable transportation-related political art.

SBC has beat the drum about the politics behind the anti-Archer project NIMBYs for 2 months, but no other outlets covered it. Thankfully, last week South Side Weekly picked up this key element of this story. Tribune's Yunus Emre Tozal, do us a favor and read this!

Chicagoans ride all year round!
We were out filming this morning by Merchandise Mart, and caught lots of folks out riding in the snow - all just in the minute we were there! Have you been out riding this week?
