This park is in Rocky River and it's bordered by King's Mill Run and Martin's Way of Center Ridge Road. I couldn't find it again but Bill's cousin Andy and her husband Brian live in the neighborhood. The day we went was rainy, but the kids didn't care.
What's good: Totally enclosed. Parking is close by, but it's set back in a housing development so there's zero traffic. Toddler climber and big climber. Lots of motor planning activities--steps, little stairs, balancers. Good slides. Pavilion for snacks.
What's bad: NO SHADE. In the summer, you'd be roasting by eleven. Other than that, this one is a winner.
Grade: A-
