It's in Death Valley, I don't remember what area of the valley it was, since I wasn't really looking at the signs. (I've got a bad habbit of that, when I'm not the one driving, I've got no clue where I'm at, haha!)
Here's a wide shot (28mm, full chip) of one area, the hills in the distance is where I aimed for a few of the long shots. The hills kept on going around almost 280 degrees from the path I was on, this is just one side of them. It was right on a (quite popular I imagine) overlook off the main road, as I was leaving 3 tour buses pulled up, haha!
