Interesting Andy as that break-out of H & M was in the Moose Jaw/Regina area so the guns being used were probably from Depot Division in Regina. I remember having the wheels and bottom of our car sprayed with some chemical and if you had got out of your car you had to walk thru a pan with about 1/8 of a inch in it to kill anything you might have picked up. There was a contractor in Moose Jaw Ken Tracey who was a explosive expert and he used exploisives to blow huge long pits where the cattle sick/healthy were shot. Ken also was the person who taught the troops about explosives and I remember him telling me some great stories of funny incidents. The day in 1952 we left for holidays in ther USAthey lifted the disenfecting program and I remember going by "stations" where they were dumping the chemical in the ditch beside the road. Today we probably know that chemical would be extremely dangerous to dispose of in that way.
