Hi bluegrasslass, head over to the WV forum and look around for the posts about Harpers Ferry & Shepherdstown. Take a look at the posts I made the other day:

So much depends on the times you have to commute and the type of home you want. I don't know how close the MARC would get you to your work, you may have to get a bus from the Garrett Park station. I think the train leaves here (Duffields) about quarter of six and gets there at about quarter after seven. But if your workday allows you to avoid the heaviest part of the rush the drive would probably be a little shorter. I used to commute to the Quince Orchard / Clopper Rd. area. Arriving at the shop about 7am it would take around 50 minutes, but that was in the late '80's.
