Lol! I got you, Ken. Hmm ok, something brief...
When I got to Nha Trang in January of 71, the US was already starting to turn over its bases and assets to the South Vietnamese. If I remember correctly, the 15th SOS departed and the 3rd SOS became the 90th SOS, or something like that. Because there was no longer a base command at NT, 1st Flight Detachment with its 4 Duck Hook aircraft (also called Black Bats) fell under operational and maintenance control of the 90th with their 4 Combat Talon aircraft. By then, most of the base was already controlled by the South Vietnamese.
Our CBPO was at Cam Ranh Bay, about 20-30 miles south, so anything to do with our pay or other matters, we had to drive there, which took us through a large rubber plantation that was frequently the site of VC ambushes. We always wore flak vests and carried M-16s when we traveled. Fortunately, we never had any trouble but we didn't drive on the roads any more than absolutely necessary. Mostly, we caught rides on the medevac helicopters that routinely flew between NT and Cam Ranh Bay. That was exciting and fun, because when leaving CRB, they often flew about 10 ft over the water along the beach to get a look at the stewardesses from the freedom birds ("round eyes" :D).
Our main entertainment in the evening was sitting on top of our bunker and watching the Army shoot at the VC wandering around on the mountainside or in the paddies between the mountains and the river. The Army had a huge searchlight on the hills south of Camp McDermott and almost every night, it lit up the mountainside searching for the enemy. Then the 40mm guns would open up and you got a colorful display of red and green tracers arcing toward the enemy. When I first arrived, there was an old WWII 155mm Long Tom in a small Army detachment just north of our compound. When it opened up, all our buildings shook. Then I understood why there were metal straps around all the fluorescent fixtures.
Anyway, I could go on...and on.... but I won't .
Cheers and sorry for getting long-winded,
