I grew up near the area described (Buri Buri) in the 1960s, but I don't remember quonset huts. I suppose they were of no interest to a child. I do miss Pee Wee Golf, which was in the same general area.
While not quonset huts, there were wooden barracks structures at SF State University about 30 years ago. Long gone, they were evidently temporary housing from the WWII era. I seem to recall these being demolished while I attended SFSU.
