Sounds like you had a fun mix of USFS car-camping, established backcountry sites and less established backcountry sites. A nearly complete cross section of camping in the WMNF.
Tin Man, did the 13 Falls or Liberty Springs Caretaker tell you about the AMC's group notification system for their backcountry sites (or did you know about it before)? Its definitly a good program to mention in this thread for other organizations thinking of taking groups to a caretaker site in the White Mountains. It can help both the caretaker and group if the AMC knows a group is coming.

P.S. Please tell me you went cliff diving at 13 Falls (or at least swimming)
