There are 30 major league baseball parks and Darren O’Donnell plans to see them all in one season — on a bike. He started in Seattle after quitting his job as a Bellingham food co-op (they wouldn’t give him the time off) and he’s made it to Florida with 12 parks done. His father is sending letters to the teams’ front offices, inviting them to meet O’Donnell when he arrives. O’Donnell is tweeting and updating his Facebook page along the way. He expects to reach his final stop in St. Louis on September 25th and doesn’t plan to bike home.
