This place is a jewel in the rough! When you arrive it looks like an old modular school but once you enter it is just amazing! My granddaughter and I went last year when she was four and again this year because SHE requested it!! They have all kinds of different rooms for different adventures. WE love it and will return anytime we are in the area. There was a lovely gentleman taking the admission fee (VERY small!) and he was so interesting I would have gladly just sat and talked with him all day. Please if you are anywhere near it go!!!! Can't say enough about it.
You can wander for hours or just hit the kids stuff if you are short on time! But trust me you will want to go back and read all the available signs! It is amazing how much is in this space!
