I expect some stares as we walk into the bike shop, and we get them. My companions are both blind, leading with white canes, and one is rolling in his ailing mountain bike. I’m also not surprised when the salesman approaches me to ask what we need. But then one of my companions, Daniel Kish, answers that he’s looking for a new tube “24 inches, latex, with a Presta valve”. The salesman quickly realizes that despite appearances, Daniel is the experienced rider.
