" Mileage craziness is a serious condition that exists in many forms. It can hit unsuspecting travelers while driving cars, motorcycles, riding in planes, crossing the country on bicycles or on foot. The symptoms may lead to obsessively placing more importance on how many miles are traveled than on the real reason for the traveling...On foot, in a van, on a fleet motorcycle or on a bicycle, a person must be very careful not to become overly concerned with arriving.
