I have joint placement of my HS daughter (three weeks on/three weeks off); the on weeks I have to drive her to school, so i only get to bike-commute every three weeks (bleah). I really just started bike commuting (again) in earnest this summer.
Here in Madison, the morning temps for my 8.25 mile ride these days is between 29-34F No technical gear save for a rain/wind breaker over an old fleece over a pullover (forgot my work shirt today *grr*) I still have to get the hang of the gear each day and fresh gear (shirt/socks) to change into. I may look into these Triflex tights as riding in pants is okay but a bit cumbersome.
My ride is part 'suburban' neighborhood, then a few miles of commuter bike path (very buccolic), then thru campus, then a nice wide bike lane, thru a park, over some rough tracks, past the weiner factory, around the airport, and I'm there. Next I need an alt route for variety (the city is completing some new paths thru the isthmus)
I can keep my bike in the room where I work (I feel for you big city folks who have to shift yer bikes around or lock it outside)
