Arizona

This is home to the Grand Canyon, I really want to visit this and if I feel brave enough, go on that glass skywalk.
(by the way I read somewhere that it's obscenely expensive and very crowded...)

Perhaps we can drive Arizona Highway 179 through the Sonoran Desert through Sedona to reach it? Something like this?
Red Rock State Park... and so on. There is such a lot to see in this state!!!

We could end our trip with this scenic drive and then go on to Las Vegas - Death Valley National Park and end point Los Angeles to fly back home. What do you think, Joy?
