Biggest: Nellis AFB - over 10,000 people on base if you include civilians
Best: RAF Wildenrath in the late 70s, early 80s; height of the Cold War, fight hard but play hard.
Bonniest: Now I'm struggling but Wattisham was always a homely place. If detachments count, Dal Molin was in amongst the nicer ones.
Bleakest: Stanley just after the war without a doubt; even with the Coastels in place.
