If you follow Highlander58 on Youtube you maybe be aware of another bear incident at the Watauga Shelter. This shelter was apparently closed a couple of years back due to bears getting into food. If you click on the link below and go to the 33min mark you can hear what happened. Apparently a couple of bears came into the shelter and managed to get at least one food bag despite it being hung. They also destroyed 2 tents looking for food. At the end he notes that rangers were made aware and are likely closing that shelter again. It sounds like these two have already associated humans with food beyond the foraging in dumpster stage. It would seem a convenient place for rangers to set up and deal with them directly, IMO.
