Had four floors, all were pretty short to walk through. More of a place to take your cjildren too but still good for the price and it's right next to a parking garage so it wasn't too horrible. Just a place to kill time.
Yes! Go! This is a very very interesting natural science center and is also an excellent place for well behaved children and also those from other parts of the country and other countries as well. Take comfortable shoes and spend some quiet time slowly. Look and learn.
I have a 9 yr old son that has loved this place since he was 2 years old! Just visited again today, and admission used to be free but that's no longer the case. $4.00 for adults and $3.00 for kids for 4 floors of history/entertainment. Great little gift shop also. It also costs to park in the parking garage...
