[AT] Preachers and Dynamite?

Larry,  I remember well when I was a kid, farmers using what they called 
"ditching" dynamite fired in a sequence to blow ditches.  Apparently it was 
a particular grade of dynamite.

that "Uncle Jim's" technique for cleaning irrigation ditches came straight 
from the Blaster's Handbook.
