I need to find a kid-friendly spot in the Berkshires to meet friends coming in from out of town next week. A playground with space to run around and good play structures is all we really need, but a pavilion or gazebo in case of rain would help and so would rest rooms. Maybe a park with a beach or a stream? Kid-friendly museums? Something near I-90 would be better than anything up toward North Adams. In the past we've done the Rockwell Museum and the Botanical Gardens, but we've had trouble finding other spots. The kids range in age from 3 to ~7. Any suggestions would be soooo much appreciated!!!!!
(We're coming from Northampton, they're coming from somewhere south of Albany.)
