I'm not quite sure what I was expecting for Saguaro National Park, but this wasn't really it. I visited the eastern portion of Saguaro National Park, which is right on the border of Tuscon, AZ. Essentially this visit consisted of an 8 mile loop road that went through a bunch of desert terrain. It was pretty cool to be zooming downhill past a bunch of really sharp plants on either side.
The actual "saguaro" forest has been coming and going since the creation of the park. Apparently a variety of environmental factors have caused a lot of them to die off, creating much less of a forest appearance. Then, restrictions on grazing rights in the park have caused an increase in the number of new saguaro plants growing, so we'll have to wait and see if the forest can recover.
