All the exhibits that we saw where very clean, inside and out. All employees giving talks were well spoken and easy to hear.
Parking lot was mostly full when we arrived but still parked pretty quick.
Admittance was 20 for adults 15 for kids over two. If you can find brochures, it's $3 off per person. Either way, I thought it was appropriate for what you get.
