I'll be damned. You are right. When first stationed there it was f-4's in Cam Ranh. I just found an old Kodak Carosal with 35mm slides from Cam Rahn and Phan Rang. Phan Rang was f-100's alright. My mistake. My memory is very fuzzy on the aircraft at that time. Thank goodness for 35mm slides that I took. Did you ever have a shop chief Tsgt. Yarbrough?
