Apart from visiting wineries - of which there are a few - we drove down many country roads, while we were selling the idea of Gloria, the SatNav to Keith and Amanda.

One of the places she took us to was The Petrified Forest. These 'trees' were submerged by lava from a nearby volcano, three thousand years ago. The giant Redwood trees all fell in the same direction, and over time, each cell of the wood was replaced with crystalized silica, until the tree was no longer wood but stone. It was also submerged by sea for many years. The whole site was rediscovered in 1871 by 'Petrified Charley', who eventually made a living out of showing it to others, including Robert Louis Stevenson, who seems to be quite important in this area!
