I'm planning on riding from Williamsport, MD to Phoenixville, PA in a couple of weeks. I'm looking for a route that will take no more than three days and get me safely over the big mountain range that runs east of Hagerstown and west of Gettysburg. I've looked at this:
which gets me to the PA Bike S Route, but is there a better alternative? Is riding further in Maryland before crossing the Mason-Dixon line an option, and if so, do you have any route suggestions?
