Inside 10-12 hours I’ll drive.
Add security time to actual flight time and luggage retrieval time, rental car procurment, etc, then factor in the what ifs of flying, weather at your destination or distant hub, secuirity alerts and such, THEN factor in the convenience of leaving when you want to or need to and the drive becomes more and more feasible.
That's my policy, too. No ringing phones (my cell is off), no knocking on the door, no one talking to me when I have something else that needs to be done. The solitude is nice. Besides, I like to drive and see new country.
