Well, "Aha! Gotcha Bitch!"
There is no such thing as a PM. He simply doesn't exist. Everything may seem great, but the deeper you dig, the more likely you are to hit a gas line. Once you realize a gas line is present, you can take precautionary measures and find new land to dig up or you can be a dumb ass and keep digging until shit explodes. I choose to walk away.
I live to dig another day.
