DC to Montana round trip X 2 plus side trips from MT to the Oregon coast X 3. Carry a cellphone, water, extra oil, gas filter, distributor cap and rotor plus some tools and good ol' duck tape. Make sure your tires have plenty of life left in them plus you've swapped all your fluids and lubed the thing over good. It'll be a blast unless you've got back problems, it takes the jaws of life to get me out of the stock seat after about 3 hours cruising. Plan your route out carefully and use this and the other Zwebsites to line up help along the way should trouble arise.
