I don't know about the drilling end of it but the service part is going crazy right now, taking home about $8000 to $9000 a month.........( . )( . )......I always have spent my last check before Christmas on my girls and they are going to love it this year more ,4 grand on 4 girls! I love to spoil my girls as you can see, they use to think all parents spent that kind of money on each kid......
