Anne, I was there from Dec.65-sept.66 working in the AGE dispatch/minor maintenance shack on the flight line. I remember a few times in '66 when weed killer was sprayed around the shop area, fuel tnaks and crate blast fenses to keep the growth down. Also, there were times that they went through the hooch area with hand sprayers to kill off the growth around the laterines and hooches. Hope that this helps you some. If you need anymore, I will be glad to write it up. FWIW it was used rather freely and often in the wet growing season.
