nvubu,
Not Bao Loc. As an aside, I thought myself quite knowledgeable about airfields in South Vietnam, but I had never heard of any of the suggestions above - nor my "mystery aerodrome" come to that. It is amazing how many airstrips there were.
I have not been able to find Bao Loc, but given the description in this article, it can't be far away from my challenge:

The strip is north-south with the mountain to the south. It is currently the "main drag" of a small town which has a different name from that of the airfield. The airfield name is the same as its parent airfield to the west, but with a suffix added. The small town's two-word name would be considered amusing/risqué to English speakers who are not familiar with Vietnamese. In fact, the first word is a fairly common girl's name and the town's name has been co-opted by a coffee shop chain, which causes amusement to tourists in Saigon.
