First night camping: a rough start. All the RVers fill up the campsites, so we were turned away at Catalina State Park and ended up at this scenic RV park in Tucson

The broad expanse of Saguaro at Tucson Mountain Park

Ocotillo Sunset

The view from the Tucson Desert Museum

A very cool sculpture that shows the evolution of birds

Quail singing

If the temperatures get below 32 deg. for 24 hours, the Saguaro tissue freezes and dies. Often the arms succumb first...

....and then drop and die.

Saguaro National Park. Very impressive place.

Here you can see the internal "woody" skeleton
