If your short on time, fly to Anchorage and rent a bike. Its cheaper in the long run. We paid 500 dollars round trip from Cincinnati last spring. If you ride, the trip is going flog your bike with at least 10,000 additional miles. You'll wear out at least two sets of tires and a chain and sprockets, and several oil changes. You will have the cost of food and camping/lodging along the way. But mostly, your going to burn a lot of valuable vacation time, which is better spent riding the good stuff in Alaska, rather than crossing the endless plains on the slab to get there. If you're in a hurry, you're not going to have a chance to spend the time in Alaska that you really need. You probably won't take that side trip to McCarthy, which was the highlight of our trip.
