How long do you drive in a day?

When I was young, I used to drive as many miles per day as I could, focused on "getting there" with limited vacation time and not really enjoying the drive. The semi-harsh ride and often hot weather and rough highway surfaces frayed our my nerves and was tough on our little kids. It took me two days and lots of cigarettes to unwind and relax once we "got there". Over the years we learned to make R&R stops every 200 miles and plan ahead as to where we were going to park for the night. It's a pain to search for a place with vacancies at night when are dead tired and road weary. 300-360 miles per day is a good
average especially with restless little kids. I have learned to enjoy the scenery while driving in a relaxed, yet alert, manner. Have activity books, etc., for the kids to keep them occupied underway.
