Our YMCA membership entitled us to free admission to the Museum of Science and Industry, aka MOSI, anytime in the month of October. We didn't want to pass up on the offer and finally made it there last weekend. We had been once before, for the Mummy exhibit with BeBe and Grandpa, but didn't get a chance to see the rest of the museum.
While we were there we explored the children's science center, went to the moon (mission: moonbase), experienced a hurricane and tornado, and visited the butterfly garden. There was so much more to do but we had had enough for the day.
When the kids get older we'll have to come back for their ropes course and zip line, and maybe get in an IMAX movie experience.
