Haha....yeah. What is up with that?!? The first time we did the trip, (we start at MM 0), we spent maybe close to an hour looking for that darn thing. None of the locals knew what it was let alone where it was! Most folks did not really know what the C&O Canal was. We were right besided the building you spoke of when we asked people. We wondered off but eventually came back to the building and somehow ended up going on the other side of the building and found it. You would think they would put of some signs for it.
For what it is worth, our second trip we used a shuttle service who "specializes" in the C&O/GAP trail and the driver did not know where MM 0 was. He knew how to get us in the general area. We had to show him where it was.
