About three years ago, Miller's phone rang. "I just talked to Don Castro," said the guy on the other end. "I have what's left of his Red Line-framed Triumph." Miller's heart just about stopped. The guy's dad had the bike. He rode it in some local races, and then parked it. He'd sold the blown-up engine years ago, but aside from a smashed downtube, the frame and swingarm were intact. "I asked Don if he was interested in buying it," the guy told Miller. "He said no, but that I should call you." After checking to make sure he was still breathing, Miller got a price and promised to call back later that day. "I had to check out his story, so I called Don. Everything was legit." Another piece of the puzzle was in Miller's hands.
