This was the funnest place ever for my girls, they are always asking to again!! It is the Discovery Museum at the Gateway! They had so many things to do, I think we were there for at least 8 hours, no joke and it went by so fast!! Ava's favorite part was when one of the volunteers helped her build something cool. Makayla loved the huge LEGOS and when she built them to her little hearts desire...she ran right through, but don't worry she would do it over and over again :)
