I just read this thread for the first time, and if you need another in MD, I'm here! Am also willing to travel; I'm thinking I need to ride the GAP from Pittsburgh to Cumberland; after Cumberland, I think it'd be an easy thing to get Maidai to, say, Washington DC via the C&O Canal Towpath, as I know there are a bunch of TEers (or some, anyway) who ride the towpath.

Or to/from York/Baltimore. That's another ride on my list to do.

I don't think this will be necessary, but since my son is in school in western MA, I could also provide a link between that area and the DC area if needed.
