The Arizona trip was good. I put eyes on 60 buildings, confirming 46 as thin-shell concrete. There are over 600 photos in my editing queue. I stayed in Albuquerque on the way out and back, 3 nights in Tucson, and 5 nights in Scottsdale. (Scottsdale is part of the Phoenix metroplex.)
I took a flight in this WWII aircraft, a C-47 cargo plane. This is the military version of the Douglas DC-3 airliner.

That aircraft has been on my bucket list for many years. The flight was a bit bumpy, and that old aeroplane definitely moved around a lot on all axis -- pitch, roll, and yaw. This particular plane had been fitted as a corporate airplane for Hoover Vacuum after the war, and retains the 1940s cabin. I would have prefered a more authentic military interior but you take what you can find with these old planes. The ride was bumpy enough that I didn't unbuckle and walk up to the cockpit for a peek.
The flight was at Falcon Field, a bustling general aviation airport that started as a WWII training airfield. The Commemorative Air Force owns and operates the C-47 and they have a nice museum there as well.
In Tucson, I was surprised and slightly terrified to see this creature walking across the parking lot while I was out of the car photographing a building.

It's probably a coyote with mange but the first thing that came to mind was chupacabra!
While in Tucson I walked the massive Pima Air & Space Museum. It's quite extensive and I had regretted not getting there on my prior Tucson trip. At most museums you might ask "Where is the
?" but at Pima the answer would be "Well, depends which one you want, we have a few of those!"
Ten nights away was a bit longer than I like, but I had active schools to photograph in three cities so I wanted two weekends for that purpose. In fact that may be the longest solo research trip I've done, at least recently.
In three weeks I'll be on my next, much shorter trip. Three nights in Kansas, with the highlight being a brief NASCAR driving experience at Kansas Speedway, a 1.5-mile tri-oval intermediate track. I'm excited for this, and I just hope I don't screw up manual shifting. The last manual transmission car I drove was the racecar at Miami-Homestead back in 2010!
Fred was certainly glad to see me return home. We've been for several long walks, with small bits of running, since I got home. He even slept with me in the guest room twice, when we came in from midnight potty breaks! (Usually, he bounds straight up the stairs to Debbie's bed.)
