I remember back in my high school swimming class many of the black students I knew had never learned to swim and were slotted for the beginner’s class - treading water, etc. Of course, there were white students who couldn’t swim, too (I was one of them at the time). But there really did seem to be a big gap between whites and blacks overall when it came to having had previous swimming experience.
Kudos to this group for reaching out. Learning to swim was one of the best things I ever did.
I learned when I was five.
