The dust devil wasn't what made us pull over to take pictures. The cool dead tree was. (Not shown, sorry.) As odd as this sounds, we didn't notice the dust devil at first, because it was so big. We've seen them all around, and they're usually small yet dynamic. This one was neither. I've used some photoshop magic to make it more readily apparent (or redly apparent).
That grey line heading up from the mountains is the dust devil. It was big, to say the least.
After we saw the devil, we saw a field full of plants. Had no idea what they were, as they looked completely unfamiliar to both of us. The occasional white flower here and there, but mostly just dark green leaves. Then I saw something white that wasn't a flower, and my brain finally made my mouth say: "cotton!" We had never seen actual cotton plants before, so that was pretty cool. (No, we did not pick any, nor did we have any gin.)
At this point of my rambling, I'd like to point something out. We are now "Arizonans" as well as "Tucsonans". How boring. I want to know who decides the monikers given to state residents. "New Yorker" sounds active (as well as magazine-ish), but "Arizonan" is just... there. I'd rather be an "Arizoner". Sounds like I'm doing something. Same goes for "Tucsonan". Dull. Why not a "Tucsovite"?
