(Also see my comment to the post, below.)
Alamogorgo is the income disparity capitol of America! There's a big retirement community, and they mostly live in the "good" part of town, where the homes are big ranch style places with elaborate desert fronts and expensive cars in the driveways. Right up the hill are Cloudcroft and Rydoso, which are vacation places for rich Texans (nice and cool all Summer, lots of golf and a horse track).
Then there's the Working Class neighborhoods in the "flats," and lots of poor Whites and Hispanics. Everybody seems to get along ok, property crime is high but there's not much violent crime. (Except between people who know each other, some people shouldn't drink! Plus the domestic violence associated with poverty.)
So, with all of the prosperous geezers around it's a good place to find medical care and decent restaurants.
Interestingly, the entire giant valley is 4,800 feet above sea level, so things can get a little breathless.
