I hear you, I usually pull off the return home in one 12 hour shot, just couldn't do it this year, I had to make a stop at the Quebec/Ontario border for a 1 hour power nap.

I saw the Quebec guys hanging around, gave them a wave and continued on, got in my driveway at about 7:30am, unloaded the car, slept for a couple hours and went to work at noon. I was out as soon as my head hit the pillow last night.
