Highway 8 from San Diego to Yuma follows the US/Mexican border and as we head east, the terrain changes. I had 'Google Earthed' this section of road before we left on our trip and I knew what to expect, but still found it very interesting. The highway is divided here by a quarter mile or so.
As we came out of the rocky area, we descended to the desert and were presented with breath taking views. It must be brutal here in summer.
It continues to be very bleak and lifeless until we get to the Imperial Valley where the irrigation from the Colorado River brings the landscape back to life. It is flat here with mountains in the far distance to the north.
We were amazed at the number of RV's pulling trailers here, all heading back west to San Diego and LA. We realised later that they had all been at the Sand Dunes with their dune buggies. 'Thousands' would not be an exaggeration at all.
