I only just noticed this particular part of the site (bit sloooowww).
Last year we drove from Adelaide to Darwin again although it was our first time with the kids. We stop at Coober Pedy and Tennant Creek overnight and unfortunately have never had time to stop and do any sightseeing enroute. We are doing the trip again next month, and we still won't get to sight see. :sigh:
I posted some picks on flickr for the rellies in the UK.

You can see them here.
