I have lived in the Milwaukee area for 9 years this fall and have never gone to the domes. Yet as I drive to work I can see them in a distance, and I usually think "I need to go check those out." It has always looked like a good place to go exploring. I have had planned playdates to meet up there in the past that have been cancelled because of sick kids or bad Wisconsin winter weather. I finally made it there. Jason and I packed the kids in the car last week and went to the domes.
There was a savenger hunt activity to complete while we were there. Honestly I don't know who had more fun finding this hidden objects.
We had fun. It was just the right size to let Grant and Norah explore and not too busy.
