We've been traveling around San Diego with my father-in-law's GPS. Occasionally, it provides directions Ed is willing to follow. More often, it provides an excellent source of argument for Helen and Connor.
"I call holding the GPS!"
It has also provided a bit of comic relief.
A few days ago Helen hollered to Ed "Watch out for the fork in the road! It's coming up. And a knife, too."
Unlike the built-in GPS in our car at home, this GPS shows both the speed limit and the rate of travel for the car. From Connor, we hear "Dad, you're going 56 miles per hour and the speed limit is 55. I hope you don't get a big speeding ticket!".
For the love of backseat driving everywhere,
