My information source found somebody to investigate. I would say "boots on the ground" but I suspect the person who investigated used a drone.
My information source informed me that no tents were found at any of the three locations.
Maybe there never were tents. That is possible.
Maybe it was fun in September and October and they decided to find better quarters with the cold weather coming in. That is also possible.
Maybe the locations were incorrect (although they seemed like very reasonable places to me). This seems less likely.
Even though it leaves egg on my face "...no tents at this time..." is the best possible outcome for all parties involved.
