Our experience was less than ideal because a fire alarm was sounding the entire time we were there. Apparently the employee who has the key to shut it off wasn't there. The kids also thought it was "boring." There was a lot of interesting stuff there and I believe if the alarm hadn't been so loud we could've pointed out more of it to the kids.
After we were done with the museum we checked out the river.
We bought the kids a couple books at a used bookstore, then went out to lunch, so the trip wasn't all bad!
