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
Looking south into the South Damen underpass bike lane at 14th St. It is full of ice about a quarter to a half foot deep.

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.

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!

Archer Ave Bike Lanes Tension Fuels Political Ambitions
Some opposition to the pedestrian and cyclist safety improvements have been coordinated by the politically connected pro-charter school Urban Center and attempts to unseat the local alder and mayor.

Baseball slugger Babe Ruth reflecting on buying his first bicycle after getting his first paycheck from the Baltimore Orioles minor league team, and steering actor Gary Cooper in Hollywood, circa 1942.

#BicycleBirthday Babe Ruth
Born on this day February 6 (1895-1948)
Quote from Babe Ruth: "I went out and celebrated, just as soon as I got my first paycheck - $100. I bought a bicycle, something that I had wanted and often prayed for through most of my young life. Most of the Orioles, of course, had cars, but none of them was as proud as I was, riding the first possession of my life through the old streets of Baltimore." Babe Ruth straddling a bicycle with Gary Cooper sitting on the handlebars.

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?
