As I make my schedule I would mail packages to the post office closest to where I plan to visit. You can request that packages be held there for you, so long as you pick it up within a few days of its arrival. Food, spare parts, Imodium, etc.

Besides that, I'd be sure to bring lots of duct tape, zip ties and bailing wire to keep my bike in one piece

Emergency parts can be overnighted as needed.

Are you planning a motorbike vacation Deacon? I'd like to bike the Lewis and Clark route from St. Louis to the Pacific.
