Living in the Mid-Atlantic region, I always like visiting the Southwest because it is so different looking. Coming from a fairly green area (in the spring at least) visiting such an alien-like terrain with hues of pink and beige, is fascinating. It's a different way of life in a very different terrain.
I have made multiple trips out to the the Southwest, especially Arizona, and every time I'm interested in finding new things to see as well as revisiting places I've already been. Like how Monet would paint the same scene several times in different conditions I like to revisit places because maybe the light will be different this time, maybe the weather will change how the rocks look, maybe an interesting animal will move through the shot. I'm no Monet, nowhere near it, but his interest in revisiting the same place knowing it won't be the same is an interesting concept. Plus when the food is so good it's always worth traveling to the Southwest.
