Well, I'm in the lower northeast, temperatures aren't above freezing and we have had an ice storm and I'm still biking. Its a little slippy but no falls yet. Funny thing is two co-workers live on my block. Two of us bike, one drives. The driver is a marathon runner so has no physical excuse to drive to work. The other biker sometimes walks when the snow is deep. Today, the bikers biked, the car driver took a cab. It isn't the car free status that prompts a person to use the cab when the ice storm comes. When I came in with my bike the car driver was in the middle of telling everyone how the cab was a necessity because the roads in our neighborhood were too slick to drive on. "Even the cab driver didn't want to drive down Iowa Ave.". I had just come down Iowa Ave. on my bike.
