I'd drive up to ninety miles in light traffic conditions only if it was for a career dept, if it was a 56 hour workweek or better, and if they had a good leave policy. That 56 hour/week schedule had better be WOWOWOOOO (24's), so that they couldn't hold you past 12 hours. If they do straight 24/48, there had better be Kelly days, otherwise you're always recovering the first day, and the next day you're always going back to work. Trying to get a week or more off is difficult with a 24/48. With the WOWOWOOOO variation, you only need to take one day off to get six in a row. Take another day or bang in and you've got eight days.
Otherwise, if it's 8, 12, or 16 hour shifts, then I'd eat a bullet if my commute was more than 30-45 minutes under normal circumstances.
