Trips such as this should be well planned and organized. That's according to my wife. Not me. I'd rather have everyone hop in and just go for the long ride. About to venture the unknown. On the contrary, Anna hates it whenever I'm in the mood for this sort of spontaneity. But we still go, nonetheless.
Anyways, what's there to see in Yuma? There's the occasional small towns with narrow roads. On the way was nothing really interesting. Some greens but really, hardly any vegetation. Occasional mountain ranges and a LOT of barren desert wasteland on the outskirts of the city.
So why go there? Because, it's Arizona. Another state. Closest to San Diego. Why not?
