JTMcC, Didn't mean to knock your lifestyle. When I was younger and single I spent quite a bit of time chasing government contract work and I don't regret doing it. I even had quite a bit of fun doing it. It's just not my thing anymore and one should consider if it fits them before taking such a job. Maybe that has something to do with the growing demand for people who will live on the road.
It can be a great career. Good pay and benefits. A great way to get experience and looks good on a resume when it's time to make a change.
