Metropolis is a little less than an hour drive from my hometown. Even so, I've only been to the statue and museum a couple times and I've only been to the Superman Celebration once. I have a picture of myself at the statue somewhere but this is the closest I can find.
There are some interesting pieces in the "Superman Museum" but it's a bit like paying money to see a Superman hoarder's shitty, unorganized basement.
At least it's better than the "Superman Exhibit" at the Cleveland Airport. Yep, that's all of it.
(Sorry for the blurry picture. I was in a rush.)
