We were lucky to only have 1 rainy day during our trip. On that day we took the T over to the Museum of Science. To be honest, I had done very little research on this museum. I heard it was great and I knew that it was free with our local museum membership. Holy cow, it knocked our socks off. It was HUGE and I would guess about 95% of the exhibits were interactive. Cole had a blast learning about all sorts of science stuff.
