Beneath the wooden boardwalk where Syren Nagakyrie, 40, was on a hike through Lettuce Lake Conservation Park in Tampa, Florida, dark shadows of fish moved in the vegetation-clogged waters, while red-eyed herons strode between the cypress roots that stuck out from the water like knobby, twisted knees.Nagakyrie, who is nonbinary, pointed out a turtle sunning itself on a log. But to see the wildlife, Nagakyrie’s mother, Vickie Boyer, 59, had to lean out of her wheelchair and peer through cracks between the wooden railings.
