Amateurs they are, we once buried a 10 wheel International with a drill mounted on it so deep I had to roll the window down to get out. It was where the Stil plant is now. At the time it was a pine forest with no drainage. The boss and the surveyors had been driving around in it in a Toyota pick up and told me the drill would go in with no problems, I walked the woods and told them I was gonna get stuck. Boss was trying to impress the Stil people and told me to get in there and start drilling. I got about 60' off the road and felt the front going down, tried to back up and the back wheels broke through the root mat and the thing sank 5' in about 5 seconds. Boss called a contractor who brought out a D7 which he promptly sank, he sent for another D7 which he also buried. Finally another contractor to bring out the biggest Terex dozer with a 200 ton winch that sat on the road and winched everybody out. Took 4 days to get out and the truck was in the shop for another week replacing all the air lines that got tore off. We ended up drilling the site with an ATV mounted drill which got stuck every time we moved it, but it had winced on both ends.
