Sorry for the late reply, I was without the internet for a week, and then just got too busy.
Galv, Mary and I both share fond memories of our US visit, we have fond memories that include meeting people and some of the natural sites, Places like Yosemite, Grand Canyon are simply spectacular. The abundance of fresh water makes some picturesque scenery. Water is what differentiates Aus and US.
Erik, It would be great to catch up again.
Groomer, jimbo, we certainly enjoy meeting new folks so we will keep you in mind when we plan our trip.
Chris, yep you will be one of the first stops, and possibly the last!
