Head up into PA towards the Yellow Breeches. Start there and explore the Cumberland. There are also some rivers in MD near you, the Savage and some others up in the hills. There is a published fly fishing guide in Maryland you can get at any book store. It'll put you on top of them (but that's no fun). Shame the Susquehanna is blown, great sulphur hatch there the bass get stupid over (some summers).
