Aside from having been there for tech school (46 weeks), I'd have to say Lowry airfield.
TDY at England AB for 6 weeks prior to heading to DaNang was a good time. The PMEL shop was shorthanded and swamped. They requested a couple guys. By the time the request processed, they were all caught up so we really had just about nothing to do and got a lot of time off.
mgentry, here's one of your babies that made an unscheduled landing at DaNang in early 72 IIRC. Scuttlebutt had it that a SAM missile was stuck in the wing. No one ever confirmed that and nothing could be seen from our side of the base but it made for interesting conversation and speculation that we would be hit that night (we were not).
