I've always wanted to visit the Noah's Ark exhibit at the Skirball museum and finally purchased tickets prior to our trip. Our ticket information stated that we could enter the museum any time within two hours of our ticket time. Our ticket time said 3:30pm, but because Josh wanted to catch some of the BYU football game that afternoon we had decided that we would go at 4:30. Unfortunately for us we didn't realize that the museum closed at 5pm. We got in and basically ran through the museum. I think we saw most everything and the kids had fun, but I'm sure they could have stayed and played for much longer than we were able.
