If you leave Concord, New Hampshire bicycling due north toward Canada, passing through Colebrook, New Hampshire, you’ll come to a remarkable downhill that resembles the one in this ad. In 1969, my high-school chum Bruce Holden and I flew down this hill at sixty miles per hour. I’ll never forget it, which is why this ad is among my favorites. Bruce went first, screaming with joy. I followed, my eyes filling with tears from the wind. We picked up so much speed that we coasted for eight miles into a tiny town. We stopped and bought a bowl of pommes frites. They were delicious. Then we turned around and headed home, pedaling every inch up the hill that had been so easy in the other direction. Fortunately, and unlike the fellow in this ad, Bruce and I could shift into low gears.
