I'm back in Tucson now and a couple observations about KJBR. One, all three of the folks who worked the FBO were kids in their early 20s which I thought was really cool since most FBO people are a lot older. Second, they were really informed about the FBO and even told me that if I were to fly back in the fall or early winter, I wouldn't have a problem getting hangar space because they are building a new hangar/s.
Side note: When you walk into the FBO from the parking lot, you walk through sort of a tunnel which has pictures of the local major employers/factories of the region. One of them was an aerial picture of Jimco lamp manufacturing. A closer look revealed that the house we used to live in when I was 8 (long since burned and replaced with a trailer) was clearly visible in that picture.
