A very fun day collaborating with good friend and Esquire Contributing Editor, Luke Dittrich, for a Bicycling Magazine article about using commuter bikes to show out-of-town friends your city.

Best part of the assignment: biking up and down and up again, the steepest streets in San Francisco with a non-cyclist.

Worst part of the assignment: constantly worrying that the $10,000 Moot Comooter loaner bike might not be there after each stop on the tour.
