Congratulations from another (ex) state-er!
I made a similar change from manufacturing to state employment 20+ yrs ago, and am SO glad I did!
I was able to move from agency to agency (in IT) over time, and gained amazing insights (mostly from process re-engineering projects) about 'gubbermint' vs. private sector (eg, all large organizations suck b/c of the medi-ocracy of their organizational limits), but also truly amazed at the dedication of many really overworked state and local folks who do very difficult things for little money and less respect (child protective services and retail food safety come to mind) - granted that might be a bit tougher at DOR, but, still, keep your eyes open for transfer opportunities!
While the salaries were/are far below equivalent private sector careers; in this state at least, the extremely well run pension system allowed me 'exit early' when the 'idiot manager quotient' got beyond my ability to tolerate.
Best wishes!!!!
