I guess coming into the area on Interstate 81 isn't mandatory. It's just the way I know, coming from central N. Carolina. Comng up 95 is an option that I really would prefer to avoid as it takes me through Richmond and Washington DC traffic. My easiest path is up 29 to 81 and head East towards Gettysburg. Somewhere in Maryland the GPS guides me off of the interstate and into secondary roads. By the time it gets into PA it's basically pavement poured on ungraded land and hills, steep and twisty. Great for cars and motorcycles.
