When I did my NT I used Bikeflights to ship the bike to Anacortes. This made the flight and the bus trip far less stressful. The bus dropped me off within walking distance of my motel and the bike shop so it was very easy to get organized. I'd recommend you chose a bike shop that is close to transportation and a motel and once you are set up just ride to the trail head, be that 10 or even 100 miles.
