That lowest band of lights you see near the mouth of the canyon is a bunch of commuters getting nowhere on the 15 freeway heading out Cajon Pass.

That is a real tarantula, seen near the beginning of our trek. I was hoping we would gain enough altitude to be out of their habitat before setting up camp for the night.
We passed a lot of hunters driving up to scope out the area and one mountain biker, but we were the only ones crazy (and fortunate) enough to be out hiking.
