I have done this trip a few times. Any particular information you need? For me I enjoyed the American west and focused more on that part and even sidetracked to see the more scenic aspects on one of my trips.
Are you more interested in the nostalgia? Cities ? Or scenic?
I thought this was going to be about the Al Ain road. :P
Sorry thread hijack just wanted to say SalsB I wondered about you the other day as you hadn't been around for ages. Hope all is well.
