The numbers are based on a survey right? I wonder how they asked the question and if there's a minimum number of trips per week, for example, to qualify as bicycle commuter.

The article implies that in spite of our frigid winters, we still have a lot of bicycle commuters. I'm guessing though that most self identified bicycle commuters in Minneapolis find another way to work from December through March so the climate really doesn't impact the numbers.

If you ranked the 50 cities based on the number of commuters in January, I bet things would look a lot different. Not to dis the Minneapolis biking population, I still ran across several other cyclists on my way home last night so I don't think we'd be last, just not 2nd.
