Baltimore's Inner Harbor is considered by many an urban development success story, transforming the waterfront of the city into a tourist-friendly destination. No wonder then that the National Pinball Museum, which moved to Baltimore from Washington, D.C. early this year, chose a storefront around the corner from the water to capture the attention of locals and visitors alike.The one-of-a-kind museum is a perfect fit for Baltimore, which already boasts quirky attractions like the American Visionary Art Museum, the Baltimore Tattoo Museum and a John Waters-endorsed thrift shop called Killer Trash.
