Roam Plows in the Jungle start

Working with the plows was interesting. They would create a temporary base for all of us in the form of a very high berm. Then they would plow down jungle all day, and retreat to the berm line at night. All night you would hear mechanics grinding the plow blades to sharpen them. I believe the plowing was done after it was determined that agent orange was "not a good substance" to use, but i have no proof.
