Safe at home! Bruce Hellerstein calls it "the one and only museum totally dedicated to our national pastime's ballparks," and it's certainly the biggest baseball museum this side of the Mississippi. It's also the only one located in a home, but still open to the public (by appointment only, and just on weekends). Hellerstein's personal collection includes seats from thirty parks, bricks, photographs, postcards, miscellanea and a re-creation of the domed entrance to Ebbets Field. Not life-sized, sadly.
