M.C.
I used to live there. You have to take the kids to the City Museum!
Don't let the name fool you, it is no run-of-the-mill musuem.
I can't explain it, you should check out the website. It is hard to describe - just plain awesome! Its like a big playground and fun for all ages. There are different activities on different floors. Its a cross between an art gallery and a playground all in one. I haven't been in about 10 years but I have heard it has only gotten better.
