Nothing much today.  We saw some spectacular scenery on the way to the very basic Cactus Country RV Park just east of Tucson.  Giant boulders were stacked in unusual and sometimes precarious looking formations about an hour west of the Arizona border.  Both of us commented on the vast amounts of uninhabited land in the United States. 

We went through a Border Patrol checkpoint as we had on our way east.  This time we saw a Greyhound bus which had been stopped for a special search by the patrol.  A dog was going crazy there.  Later, we stopped for fuel and lunch and after we got on the road again we saw that same bus broken down by the side of I-10 with the passengers standing outside under an underpass.  I'll bet it was a long wait before another bus could be dispatched to pick them up.

We had another time zone change today and are now on Pacific Daylight time because Arizona does not recognize daylight time.
