Hey guys. I have a feeling Im being over-optimistic here but is there any good dirt to ride between northern MD and Philly (not as far west as Michaux -- I'm planning a DC-Philly ride). I know about the PA map showing all those dirt roads in red but unfortunately I don't have time for that sort of exploring and improvisation. Any ideas? And if there are no DS options, are there any decent paved routes worth taking? Thanks a lot!
