Who, what, when, where?

Here are a couple of photos I found in the box of old family stuff. I recognize Jimmy and myself, of course, but who are the other people? I was thinking they were taken on the same occasion, just from the lawn chairs; but now I'm not so sure as the others don't look alike. Let me know and I'll add it to this post.

I knew Jimmy would know who this was and where the picture was taken. Here's her post in reply to my question:

The four on the lawn chairs are me, Jug, Mike Davidson, and Diana Cahill. We're at the "cabin" (3 bedroom brick w/bay window) at Possum Kingdom lake owned by PICO Drilling Co. Mike rode down w/Daddy, Mother, and Jug because his ears were bad and he couldn't fly in a small plane. I went w/Jimmy Davidson, his wife Betty, and their little girl (and I can't think of her name right now) in a Cessna-type. That's the time I walked into Aunt Rube's and Joel asked me where Daddy was. When I said he wasn't there yet, Joel said, "Well, dammit, go home!!!".

The other picture was taken on the same trip. The Cahills--Carl, Wanda, Jimmy, and Diana-from Sonora. Carl owned Cahill's Construction Co. and did a world of work for Daddy down in that part of the world. I had a horrible crush on Jimmy. Carl was killed when he crashed the plane he was piloting about a year after Daddy died. Diana's husband was killed as well as the "real" pilot who was w/them. Carl had been flying his own plane for years.

It must have been another time that I flew in a small plane; it seems like we went all the way to Wyoming or something. I well remember that, as it was the first time I had ever been in an airplane in my life. It was pretty exciting, especially as I seem to remember that we had to land unexpectedly in some field, and wait while someone brought a part and the engine was repaired. Possum Kingdom is a big reservoir just west of Dallas/Fort Worth (and actually, before this last trip to Texas this summer, I didn't realize how far east it was). We went there once or twice; I was pretty small but I remember swimming and boating, which was likewise something pretty unique in my expericences, Roy Lee not being much for doing things outdoors. Here's a photo of Possum Kingdom from a website:

So now who was the other person whose ranch we used to go to? Was Possum Kingdom the site of the infamous giant catfish, nests of rattlesnakes and cottonmouths, scorpions in the pool, and all of that? Or was that somewhere else? Sonora, Texas? It must be because I see by the map that it's near Ozona, Texas, another name that rings a bell.
