The best place to surf in Nam is Vung Tau.
I never was there, but I did get nearby to Nha Trang courtesy of an all expenses paid vacation at the 8th Field Hospital.
When we went swimming at Tuy Hoa in II Corps there were sentries posted on the beach not for Charlie but to shoot the sharks.
I bet Nha Trang was nice. I´ve heard Vung Tau has some rips. Yet I sort of recoil reflexively at the name. Wasn´t there a lot of enemy activity down there then? Well, this is now. ´Glad I discovered...and rediscovered the place.
