Gentex has their annual Summer Picnic for their employees every year at Michigan's Adventure. We brought the girls thinking that she would have a riot. I however, was very skeptical. Bryan insisted that she could have a good time. I will gladly admit that I was very wrong. This girl LOVED the rides. She would say that they tickled her tummy. There wasn't a ride in that park that she was allowed to go on that she didn't ride.
