In my early 20's, I drove from Appleton, WI to Las Vegas while only stopping for gas and food and a quick 2 hour nap somewhere east of Denver. 28 hours and 1,820 miles in a 1996 Sunfire GT.
In my late 30's, I drove from Appleton to St. Pete's Beach, FL. Again only stopping for gas and food and a quick rest somewhere in TN. 25 hours and 1,400 miles in the current A6.
6 weeks from now, I will be taking the whole family to Disney, so another overnight road trip of 24 hours and 1,250 miles. I must be out of my mind! At least the kids will have a tv to watch and play wii on.
