+10 on the driving only when rested. Few years ago I drove 3 hours one way to help my brother in law rebuild his front porch. Nice october day, windy and drizzle all day! I was back on the road by 5pm and after an hour realized that I had no buisness being on the road. Pulled into a rest stop laid the seat back and instead of waking up to my wristwatch alarm 45 min later, I woke up to a NY State Trooper knocking on my window 2 hours later!
Turns out the trooper was my best friend from grade school whom I hadn't seen in 18 years.
