A number of years ago, I rode a charter plane ride, from Vegas to the canyon. The plane flew right in the middle of the canyon, and I took some awesome shots from the Cessna. I'm not sure if they still have those charters, but if they do, go for the most scenic ride of your life.
My understanding is that people have released pet Boas and Pythons there and they are taking over.
There are other snakes besides Boas and Pythons there. I don't know too much about snakes. But I do know, the wrong kind will kill you.
An anti-halation backing is a layer found in most photographic films. It is usually a coating on the back of the film base, but sometimes it is incorporated between the light-sensitive emulsion and the base. The light that passes through the emulsion is absorbed by the anti-halation layer. This prevents any light from being reflected back through the emulsion from the rear surface of the base, or from anything behind the film, and causing a halo-like effect around bright points or edges in the image. The anti-halation layer is rendered transparent or washed out (as in K-14 films) during processing of the film.
The lack of an anti-halation layer in Kodak's High Speed Infrared film (HIE) is the cause of the ethereal "glowing" effect often associated with infrared photography[1], rather than an artifact of IR itself.

Get a stick, about 6-7" long. Put some peanut butter on the stick, and insert it in the ground nera where the chipmunks are running. Chipmunks love peanut butter, and it sticks in their mouth. It is funny to watch them.
I have been told that Pentax DSLR cameras can use the lenses from their older SLR cameras. I have several lens for my old ME and LX camera bodies. Has anyone had any experience using their old lenses?
