We had a wonderful time here today. We took our time walking and reading and spent about 4 hours in the park. We didn't cover everything but probably 90% of it. It has been a very long time since our last visit. The weather was very nice 85 and a light breeze. This made for a wonderful day to take our time and really experience more than when its hotter. $10 for parking, veterans discount on admission with ID. Snacks and drinks throughout park. Nice clean bathrooms and exhibits. Plenty of staff for all your questions. Souvenirs and gift shops open. Picnic area. Children's learning area. Several places to tuck into to cool off as you go.
