Thanks Murray. I had thought of that, and I actually delayed submitting my resume for about a week while I thought about it. The last roughnecks I met were high as a kite on meth, and definitely big drinkers. I even called a friend whose ex-husband worked on oil fields on Alaska's North Slope and asked for her advice. She told me compared to the guys I used to hang around with roughnecks shouldn't be a problem.
I just can't pass up the opportunity for a year's experience, it's the biggest obstacle to getting hired for a full time permanent position. I was doing drugs when I should have been doing internships, so now I need a work-around. I'm just going to have to man up and deal with whatever comes my way while I'm there.
