Larry, nice work! If I remember correctly the entire munitions area was clear, so it was sprayed too, that would put the drift area in the old hooch area. When I was actually there (1966), I did not realize the distances to things, it seemed further for some reason. You are correct almost everything on the other side of the runway was in Thai controlled area and not USAF. Everything on the other side of the runway was dead and brown. Look at the "Combined" Takhli Websites, especially the "Bangkok Bob" section and look at the pictures, Ben Shuppert has some nice aerial shots posted, the lack of vegetation is noticeable compared to the satellite photo you used to make your map. Others may have some different recollections, especially from different years at the base. LouB.
