Really fascinating, written by someone slowly losing his vision. The cultures of blindness, the DIY and engineering sides of disability, the fights between NFB and the more radical blind organizations. There’s a beautiful moment when he’s talking to a blind child at a conference who tells him about finding a tomato on the ground and he wonders at the idea of the child being able to find the tomato he loves with his cane and not “crush the things he loves underfoot”.
