That's funny. Back in 1975 I was a young soldier at Ft Riley KS. Hemp grew wild out in the training/maneuver area 10-12 feet high and was referred to a Kansas Killer Weed (according to the pot heads it wasn't very good). On an exercise we were ordered to use natural foliage to camouflage our tanks. The command had no sense of humor at all over the camo job on our tanks! Rick
