Great setting by Lake Erie (we saw a good-sized snake by the shoreline), a big honkin' freighter, and the Rock Hall of Fame. Not too big and not too small. The eatery is nothing special, though we were famished and enjoyed pizza (typical institutional pizza) and a darn good roasted butternut squash salad.
The NASA section is fascinating (a bit more info. would be useful), and the hands-on stuff upstairs, which I expected to be totally kid-oriented, was informative and fun for adults, too. Not all of us saw the Rubik's cube thing downstairs, but I hear it was pretty cool.
