In Ankara (where, fortunately, I was near for all of my tours), most of the facilities were within the city of Ankara before they got the base at Balgat fully made. Between my first tour there and my last, more and more stuff was in the base (eventually virtually everything was on base). I know in Izmir, everything was downtown as they never really built a base there. Do you think that the case in Adana, before the base at Incirlik was fully built out?
BTW, if you haven't ever read it, you might enjoy this book:
From one of the reviews (pretty well concisely captures the book):
For anyone who was in the Air Force in Turkey during the late 60's or early 70's this is a must read. The book is full of humor and brought back a flood of memories for me. I was stationed at a detachment in Turkey in early 1970-71 with a Tumpane employee. John Tumpane had a number of hijinks that will keep you laughing through out the book.
