There is something always intriguing to me about the desert. I'm not sure if it's the desolation, the unique scrub foliage, the vast distances with the mountains you know you'll inevitably reach or all of the above, but I really enjoy driving through the desert.
Sometimes the road is a flat, straight ribbon as far as the eye can see. Other times there are slight rolling hills, as in this photo. Sometimes there is a proliferation of cacti of numerous varieties. Sometimes it's just scrub brush and sage brush. I especially love the desert in the spring when it's in bloom with unique flowers seen only in the desert.
