Dirt Bike Fly Fishing

[McFly]

I usually fish the Yampa River near Steamboat Springs in Colorado, I would usually hike into my spot and hike all the way out, two years ago I saw some kids riding their ATV through the trail and fishing, they had all their gear and food on the ATV racks and their travel time was 1/10 th my time. So I pulled my 94' KTM 300 dirt bike out of the garage and made her trail ready again- the first test was the N.C. Fly Fishing trail, I was able to cover Ravens Fork and Scott Creek with no problem , I would like to use my bike on waters a little closer does any one know of any off road trails close to fishing waters on the Potomac.
