You might also contact COSI in Columbus, Ohio - they had a car you could lift with a large lever as well as other fun physics stations. I recall them having an interesting outdoor space. New York Hall of Science also had a really fun outdoor space I used to bring my kids to. There was mini-golf as well as some water play for my little folks. Indianapolis Children's Museum did a big addition a few years back where they installed a series of sport-themed activity stations outside the museum, but they're only open seasonally. Super cool stuff, though.
