Interesting find today: the Telephone Pioneers of America Park. Weird name (the Telephone Pioneers Association raised all the money for the park), and seemed weird for this park to be on the list.
Well, turns out that this was the very first barrier-free park in the country. Not only does it have an accessible swimming pool, but everything else is accessible too: tennis courts, racquetball courts, outdoor exercise course, and even two “beep baseball” fields. I hadn’t heard of beep baseball before, but it’s basically a special variety of baseball for the blind. Huh, had no idea that was a thing, and had no idea that this park existed. Kudos, Phoenix!
