On a related note, Joel Rice recently interviewed blind skateboarder Thomas “Tommy” Carroll:
The area I focus on is muscle memory. I’m always listening to the sound of my wheels—what surfaces they’re reflecting off of—because that helps me determine whether I am going off course or not. Like, this ramp puts you this way and puts you at this angle. Hearing I use as a reference. I can say, okay, I have this much room to 50-50.
