This hoard is not just living off the land. Someone is providing not only guides, but food, water and sanitation supplies not to mention transportation. Imagine the huge amounts of human waste this crowd generates. The trail should be as feces covered as San Francisco and filled with trash, yet photos seem not to show this. Someone is providing massive sanitation for the hoard.
I just would not want to be in this second horde of invaders coming through downwind of all this excrement
