What doesn't it have?  Roger Williams Park has a great zoo which is just getting better with a new Wild Dog exhibit.  It has Swan Paddle Boats - haven't attempted that one yet.  There are Pony Rides and a cute little Choo Choo Train.  There is a Carousel.  But our new favorite activity has to be Hasbro's Boundless Playground.  It is designed with special needs children in mind.  The set-up is thoughtful and the activities are unique.  My 19 month-old and her two buddies had a blast.  Oh and on a beautiful day...it wasn't crowded!
