I was at Takhli RTAFB from sept 72 to sept 73 with the F-111A's during the Linebacker campanes (Linebacker I and Linebaker II).
While I was there, everywhere you went on base had a fence or baredwire area that you would have to walk next to before you got to where you were going on base. All fences that I saw had nothing but bare dirt around it, and No vegitation close by.
The peramiter around the base was not the only place that had got sprayed.
As I recall, there were several shuttle bus stops on base that were nothing but dirt as well.
That secret compound on the south end of the base with all the Concertene Bared/Rasor wire didn't have any vegitation anywhere close to it.
And a lot of people used to walk right past that place while walking up to the flightline shops.
In case you don't remember, that was the fenced in area whre we were told that if we saw that place under attack, we were to "just keep on walking and pretend that you saw nothing and to mind your own buisness".

Also with the F-111A's flying so low to the ground all the time (i.e. Treetop Airlines), It is highly possible that they could have picked up the AO overspray while on thier missions and brought the stuff back to unnkowing GI's whether they worked the flightline or the field shops.
There was one perticular LRU that had a bad condinsation problem when we first got there and it would sometimes drainout onto us GI's in the Avionics Shop doing repairs on the LRU's.
I had the stuff drinched all over me several times before we got a TCTO directive to make a fix to the condinsation problem.
Since that time,,I have found out that two of the GI's that I gotten drinched with back then has passed away and both their families belive that they were AO problems with them.
I my self have several probles, one of which is a bad body tick that started after I got back from Takhli in 1974, and has sence then gotten worst.
The VA still doen'st reconise my problems yet.
They want more proof. Go figure ?
What more proof do they want,,,,,AO was all over the base and not just on the peramitors.
