OK. With all the children screaming with delight it was noisy. And no, I wasn't able to let myself add to the screams while I ran up and down the ramps, slid down the slides, crawled through the tunnels, and watched the performers. I did have a lot of fun despite being a mature adult (69). The displays were just wild. There was lots of pop stuff from the 50's thru the 80's. Really nice architectural stuff from 19th century buildings. Bottles, doorknobs, butterflies and other mounted insects. My son and daughter told me how much I missed because it was Winter and the outdoor stuff was closed. I'd like to return to St. Louis this summer to crawl through the ironwork up to the 5th floor and slide down from the 9th floor.
