Pros: Summers are beautiful, there are 10,000 lakes.
Cons: Winters are brutal.

Bicycling magazine at one point ranked Minneapolis first, but we can't help but think that was just an attempt to be controversial. There's no doubt that Minneapolis is exceedingly cycling friendly, but the brutal winters (when it's either rollers or a Moonlander) make it difficult to give it the very top spot. Then again, they've doubled the miles of on-street bikeways over the past two years, so maybe we're the ones who are being controversial. Either way, it's a great place to visit. When it's warm.
