What you see in the picture above is a capacitor. It came out of a TV. No, people don't go out there to watch TV. They go out there to shoot TVs. They also shoot their empty beer cans and bottles and lots of other trash. Mystery solved. BTW, I know the cap came from a TV because I also found the yoke off the tube.
There are also large saguaros in that area. Surprisingly, they are not shot up. I guess people bring enough trash to shoot out there that they don't have to resort to shooting saguaros. When I left the truck, I was thinking that I wouldn't be taking many pictures. I wound up taking a lot of pictures of saguaros, though.
I'm going to go out there again. I need to start out a little further north, to avoid a lot of the pointless ups and downs around Lone Mountain. I may find something intriguing yet. Click below to see all of the pictures.
