Cat, I've read that it doesn't really make much difference west to east or east to west with regard to the winds. I realize the Jetstream flows west to east, though. I'm open to whichever direction and will do more research.

DB, Why not retire next year? Then re-enter the workforce again after the ride? Professional athletes do it all the time.
