Water bottles galore, and rags to clean my chain with. A little money once in a while, a few nice tools. Wild onions. If I ever need to make a soda can stove while traveling, there will be no problem there.

Best score ever: an unused, prepaid cell phone, in a ziplock bag with charger. Years later, I'm still using it. Even though I didn't buy it, I can add minutes. It costs $20 to refill it every three months.
