Thanks again everyone!
I definitely needed the studded tires for most of the commute. Only had one hairy moment where I hit chunk of solid ice lurking under some snow, other than that, smooth sailing on compact snow and ice for most of the commute, and bare and wet otherwise. Only added about 10 minutes to my commute. I'll get three more commutes on the snow bike, then we'll see what things look like Sunday, the rain that day may finally clear things up for my commute in that afternoon, but it's all 25-33 degrees between now and then.
Cheers!
