12. Campbell's Field

What's the closest ballpark to downtown Philadelphia? If you said Citizen's Bank, you'd be wrong. Campbell's Field, just a mile across the Ben Franklin Bridge from Independence Hall, is actually closer to Philly than the Phillies field is (say that five times fast). Home to the independent Camden Riversharks, Campbell's is right at the base of the aforementioned Franklin Bridge, and is a great reason to visit an otherwise struggling city.
