Congratulations - that is some shot.
Yes, Gary the Kimberley is spectacular. You don't see colors like that elsewhere. I haven't been there for over 20 years but perhaps next year during my LSL we'll get back there.
We spent the best part of a year there, mostly working in Kununurra, and got to see many of the attractions before the tourists moved in (eg we stayed at El Questro when they were only charging a couple of bucks a day to camp). Getting to places was probably harder than it is now but when you got there you tended to have the place to yourself.
Mike, it's a pity the tour doesn't include the Wolf Creek meteor crater. It's perhaps not the most spectacular looking place but for someone with your interests it would be fascinating.
