We have been looking forward to visiting this museum for over two years and finally took the 2+ hour drive out to Amherst on Sunday, July 21st, but we were a bit disappointed. The building is beautiful, spacious, clean, and air conditioned (a big plus this summer given the extreme heat) but the galleries are so small and had minimal appeal to us. I guess my expectations were higher given how many wonderful books Mr. Carle has written and illustrated. I wish we had gone the prior weekend when Mo Willems work was featured. Having read some of the recent reviews (after the fact) it sounds like that was a great day and packed with lots of kid friendly activities. On the day that we visited there was a story time in the library led by a children's illustrator and apparently there was a puppet show that day as well although I didn't hear about it until it was too late. My son enjoyed reading the books in the wooden baskets in each of the two galleries but we could have just as easily done that at a library. We ended up paying a relatively steep admission to just read a few books and purchase a few more from the gift shop. I think the galleries should be larger (didn't I read somewhere that the building is 40,000 square feet?) and more interactive (how about a video interview of Mr. Carle or Mo Willems explaining how they come up with their ideas and translate them to picture art?). Also, the staff that was on that day didn't seem very engaged (at least not with us). They seemed more interested in their handheld devices than in interacting with the patrons.
