If you can’t make it out to a baseball game, a stop by Clyde Doepner’s attic in St. Paul might make you feel as though you’re at one. He is thought to have the world’s largest collection of Minnesota Twins baseball memorabilia. Since his first ticket stub from the Twins opening game in 1961, Doepner has acquired over 6,000 items. He hopes to be able to share part of the collection and its history with visitors in the Twins’ new ballpark in 2010.
