One hardback was a bad idea. Two? Preposterous. Last October, the night before I left for my first overnight bike trip, I examined all the articles spread before me on the floor and glanced at my list of nearly 100 items, including clothing, camping gear, emergency supplies and food for five days. I looked at the shiny red bags charged with carrying everything. I thought of the hardcore cyclists who drill holes in their toothbrushes to lighten their load and reminded myself - for the umpteenth time - that every ounce counts. Then I glanced at the second book and woefully added it to the reject pile.
