How would you define disability?
Something that limits you due to x, y or z. Everyone has a disability of some sort. No one's perfect. Everyone has a flaw of some type. In terms of ADA, we should all be treated the same, because we are all disabled. -Christopher Noel, NYC Parks ADA Accessibility Coordinator
Many “special needs” items need not be special, they just need to be available . For example Scrabble and books for wheelchair bound, puppets for autism, a hula hoop for the blind. FatBrain toys offers ideas like these for many disabilities. Items not only need to be available, people must also know the items are available, hence the parks banner below
“The higher cost of "inclusive" playgrounds means many local governments can't afford them.”-NPR
