May 2012 Boys' Life. 108 mile bicycle trip. Small group of boy scouts. Camping out 5 nights. Some food resupply by outsiders. 18 tire blow outs. multiple broken chain links. 40 pounds of equipment on each bicycle. Some had custom packs made for their bikes. Others used conventional racks. Do I have the skills? Frankly no. I will be printing out the cartoons of how to fix a flat and service a bicycle chain. Then, I will buy equipment and tools. I already had the bags and racks. From the pictures and the clothes, it was summer time. A fleeting thought. Whether you chose a bicycle, a motorcycle, car or truck, you had better have some spare parts and skills for when shtf.
