When Don Walker heard the story of cycling Greg Impellizeri, who lost his sight as the unexpected consequence of a medical procedure, he decided he had to help. "I got in touch with him and suggested I build him a tandem, so at least he can keep riding, even if he can no longer see," said Don. A few days later Walker heard from Brooke, Greg's girlfriend. "Bikes were Greg's world, and that world crumbled. You are giving him that world back... trust me, this is MAJOR. You are making more of a difference in Greg's life than you realize." she wrote. The tandem itself will be on display at NAHBS, a fillet brazed frame with clearcoat, and definitely is worth a look.
