Brad Morgan of Carlisle, PA recently started a blog titled Motorcycle Touring in Pennsylvania. Brad provides "...a vital (and praiseworthy) public service by highlighting some Pennsylvania roads that are worthy of your time in the saddle – roads that provide a solid combination of scenery and a significant amount of fun factor!". He provides narratives, photos, and maps of roads in Central Pennsylvania which he calls Pennsylvania's "sweet spot".
A must read if you plan on riding or touring in Central Pennsylvania.
