Joshua Tree National Park California.

The southern park entrance is located 25 miles east of Indio on Highway 1, about one hour from Palm Springs. Unfortunately when we were there in September the temperature was over 100 F. so doing any of the hiking trails was not an option. There are hundreds of miles of hiking trails with camping facilities along the way, something to put on the to do list if ever we are in the USA during the winter.

Backcountry roads graveyards.

Our trip only covered a very small part of central Australia but there was a lot of automotive history on show. There must be thousands of vehicles scattered across the desert areas, this is a small selection.
