I don't remember all their names, but I looked in on a few of the shelters we didn't stay at. One new one blew me away. Two story log cabin.. not a half loft accessed by a ladder, but a rear stairwell to get upstairs!
Apparently it was full the previous night, and someone was hogging the main part with a tent inside the shelter.
Overall, I'll say the Potomac AT Club seem to be amazingly well funded and not short on volunteers! Great section.
