New state to explore

I’ll be in Maryland this Saturday so I decided to pick up a MD fishing license and head to the Gunpowder in the morning. I have no idea where to go. I’m having a hard time finding any info about the area online. I couldn’t even find any Maryland fly fishing books though I know they exist as I have seen them. William H of Eastern Trophies Fly Fishing mentions on his site that between Prettyboy Dam and Bluemount Road (MD 138), it is catch and release, flyfishing only. Sounds like where I ought to be. Hopefully I’ll have some luck this time and I won’t completely freeze. I ordered some stuff today that will keep rod guides and lines from freezing. William mentioned using Spam, but that sounds awful.
