We have very rural roots, the great uncles on my dad’s side were central Idaho loggers and mill managers. Big equipment and industrial work were common. Explosives were in common use building roads and even “cutting” very large trees that were difficult to saw. Log jams were often blown up to clear so it wasn’t unusual to be around it. My Dad’s truck company commonly carried it, delivering it around his service area. An old buddy and busisness partner of his had a dummy stick in his desk, when feeling particularly frisky, he would put a short fuse on it and roll it yep under some unsuspecting soul with great glee if he could envoke a strong reaction. One of the sides of the company had milk tankers with large stainless steel tanks. They had a large hatch on top to access the tank for periodic cleaning. So, one of there workers was an older black guy that was down in the tank with a short wooden ladder. So, (Ellis) threw the stick with a 4” lit fuse into the hatch........my dad said the worker broke every rung of the ladder getting out. They didn’t see him for 3 days.....Dad was afraid he had a heart attack, went to his house, had to give him a raise to get him to come back to work. Not many years ago (pre 911) a scale house was blown into toothpick size debris in Montana, it seems that they had messed with a trucker earlier in the week and after everyone had left for the evening he took his revenge. The house was very rural and no one knew it was gone until they came to work the next morning.
