Saguaro Splashed with Light

I've never actually stepped foot in Saguaro, but I've been to Tucson which splits the National Park down the middle. I've selected this photo because it captures my memory of the natural area pretty well; wide open landscape, big skies, those strange Saguaro cacti, and even the morning light transport me to that place (I assume this is morning light, as I think those are the Santa Catalina Mountains in the distance). I also like the simple composition of this shot, one big Saguaro in portrait, obeying the photographic rule of thirds.
