Donovan Park should be called Donovan Land. The sprawling wooden kid-world could make even the most unimaginative tyke imagine he's the ruler of a vast kingdom. Turrets, bridges and secret compartments link the more typical playground accessories: slides, jungle gyms, climbing nets, swings and the like. The park is surrounded by trees and grassy hills; shaded areas with benches will please parents. But they won't be so happy when it's time to collect the children. There are many hiding places at the playground, and it's no easy task to talk the little kings and queens down.
