Deb-
Actually, Carol is right about the old comfort station in the middle of the 2100 loop. As you pointed out, there is a comfort station located between the 1100 loop and the 2100 loop, but there is also one smack dab in the middle of the 2100 loop. According to this old map, the 2100 loop was originally a camping loop. Now, it is a cabin loop, and the old comfort station is used as a maintenance headquarters for the cabins.
Also, the sidewalk from the 2100 loop to the 1100 loop comfort station was there before 1998, as I remember using it when we stayed in the original Wilderness Homes, and then the cabins that replaced them on this loop in 1998.
