9. A tarp to lie on, a tool bag filled with an assortment of sockets, wrenches, and screwdrivers, and an ice-cold Arnold Palmer to drink can make a tough day on the trail go a lot easier. Be sure to keep any special sockets or custom wrenches you need with you. It's also a good idea to paint them some obnoxiously bright color so they don't get lost or left behind. Use your head and try to have good trail etiquette. If you can drag your broken rig to the side safely, do so. Don't rely on your buddy to carry that spare thing-a-ma-bob. Carry your own spare parts and known weak links.
