Interesting post, U90 - par for the course for you.
I would add to your list of "isolated" military facilities more than a few AF bases - Edwards, Mt Home, Holloman, Cannon, Minot, Grand Forks, Whiteman, Little Rock (it's not actually all that near to Little Rock) and maybe FE Warren. I'm sure I missed a few.
As for Army Posts, my knowledge is limited, but I have been to White Sands Missile Range (was a college intern there) and Ft Rucker.
I would guess Ft Polk, Ft Leonard Wood, Ft Huachuca (could be wrong on this one) would also make my list.
And I'm REALLY not up on Navy facilities, but I would add Patuxcent River (been there) and Whidbey Island to my list.
And I would suggest you add Yuma to your list as well.
I'm somewhat partial to commissaries - I grew up as an AF dependent and my family shopped there for most groceries, etc. I sacked groceries in the commissary as a young teenager and then became my family's designated "grocery shopper" when I was in High School (with a list made out by my mom).
But I agree with your comments about the BX, PX, and Navy Exchanges. I think they are necessary for remote installations, but they should be more like Walmart in their selection and prices.
Edit: Back in the ancient days before the internet most military families in remote locations made a lot of their purchases from catalogs - primarily Sears, JC Penneys, and Montgomery Wards. But that was also the days before UPS, FEDEX, etc, so your packages came via US Postal Service, which was slow as hell (and often unreliable if you were overseas).
Been there, done that - as a dependent and in my 21 year AF career (retired in 1991).
