Yah, I'll keep my eye on the weather. I expect chilly mornings and evenings but if we get a front like this then I would probably postpone. We were going to do the entire MD length but have decided to just do two nights with a friend of mine and his sone. Probably hop on the trail around Rt 40 and i-70 and hike it to Harpers Ferry. I've never really done any over night hiking, hard to believe.
