Moving at 80 and 90

My in-laws are almost all packed up. They are almost 85 and 92 (summer birthdays) and are moving from WA to ID, to a college town with lots to see and do, plus a lot more sunshine than Western WA. He loves to golf and she has a ton of friends over there so it's a good move for them. However... at their age, moving is more than a pain, it's down right dangerous! They've been working too hard and are totally worn out. Tomorrow they're beginning the drive over there. So if I were you, I'd get off the roads between Olympia and Nampa for a couple days, cuz here come two sleep-deprived old people to a freeway near you!
