I almost busted my ass pushing the bike into the driveway! A quick YouTube search did in fact return results showing dudes riding on the streets with snow.
A few winters ago I got caught out in heavy snow, had to abandon the bike about 3 miles from home. I reckon I could of made it but didn't trust anyone else on the road who clearly didn't have a clue how to drive on snow.
I, like Benji, used to be an Illinois boy. But (thankfully so) I found my wife in Cali and she dragged me out here. Now I sound like a jerk complaining about riding in 50F. (yeah this warm weather has made me a tenderfoot). No more -5 to chap my hide anymore.
Besides, I don't trust people in the rain here, let alone snow. Ha.
