For anyone who leads a vibrant, robust life, the realities of aging can be humbling, but to Piet Boonstra they are merely an inconvenience to be overcome in a quest to continue riding long distances. Written in an easy to read style that is hard to put down, it begins with the journal from his eighth trip to Alaska, at age 79, recounting a high-speed collision with a Stone’s sheep from the saddle of a BMW 650 Dakar. Inspiring memoirs of an octogenarian with a determination to overcome all odds and continue riding for as long as there is a road to follow. By Piet Boonstra. Softbound, 288 pp., b/w illus.
