Silvan notes:
Check the pay. Blacksburg may surprise us both. You seem to be in a spot where a job choice is soon to be inevitable. To offer unasked for advice, consider ALL the costs involved. Most VA teaching jobs require you to pay part of your health insurance, but it amounts, I think, to about $250 monthly and will cover the whole family. Depends on the deductible, as you know, in part. Remember that about 8-9 weeks of the mid-year is available to knock together projects to sell the rest of the year, too. That MIGHT replace some of the income. Hell, maybe you could drive a truck in the summer!
Teaching has its hazards and stresses. It has its rewards. Pay is rising, though not as rapidly as it needs to if we're going to replace a half-competent corps of teachers with a full group of good teachers (aznd keep them).
If you're not (both you and your wife) paying out as much for insurance, you're not eating on the road daily, you're not subject to the dangers of icy weather (when schools are closed), whenyou no longer face the stresses of driving an articulated box on wheels, think about how much more you might enjoy life.
See what the salary is, what the steps are, how seriously they're going to be on your ass to get a master's, or 30 hours beyond, etc.
Then decide. I wish you luck.
