It runs from Lake and Nicolette through downtown to just past where they're building the new Guthrie theater.
As far as winter riding, Nicolette's usually pretty good - they plow that one really fast. Most of downtown's good really fast, too. They tend to plow the snow into the bike paths, though. I ride in the bus lanes then - most of the bus drivers are pretty understanding about it. Second street by the river gets done first I think - that's where the crews get together each night for the shift changes.
