There's a fascinating spread of careers listed here, and I was a little surprised by the number of IT types. Don't know if I should have been, but I was. <shrug>
My jobs path (still not in a career track, to my way of thinking) -
US Navy Reactor Operator '91-97, Control Room Operator at a civilian nuclear power plant '98-06, Plant Operator at a water-production plant '06-current.
