I averaged 4 days per week (one exception was the week I was in Florida). It was way colder than most recent years, but tolerable. And best of all, no flats or falls.

Jan& Feb have been non-stop cold with lots of the white stuff. I have been able to bike every day up until yesterday (Feb26) because our roads and highways are narrow and worse - our sidewalks are now slick ice.
Coldest biking day was 2 weeks ago when it was -42 C with the windchill. I biked that day just so I could say I biked on our coldest day of the year. And I really wasn't cold!!
Its been another winter of biking adventure here in New Brunswick Canada but I definitely look forward to biking in one layer of clothing as opposed to 2 or 3.

Ron: You sure are a hearty breed up there in Canada. Down here in southern Kentucky, if it gets below 32 degrees F, we forget our bikes and stay inside by the fire! So far this month (Feb.), I've been out on my bike only four times, for a total of 40 miles.
