A few weeks back my wife and I were visiting my parents. On the way home, we decided to stop at the oasis to pick up some car snacks and other things. The oasis that we visit spans the highway so that you can visit it from either direction.
After I got the car snacks, I did not see my wife right away. I looked over to the center of the oasis and saw my wife watching the traffic pass under the oasis. Just as I was in ear shot, I heard her singing twangs at odd intervals. When I got next to her I figured out what she was doing.
She was playing Guitar Hero with the passing cars. As each car passed under the overpass, she would sing a different pitch much like you would if you were playing a bass guitar. There are three lanes each of which were assigned a different pitch. Each car travels at a different speed which makes playing Guitar Hero this way a bit more challenging. As each car passes under the overpass you would sing the pitch. We stood there both playing Guitar Hero for the next five minutes or so, then proceeded to get into our car and go home.
So if you are traveling by car this weekend… stop at the nearest oasis and give "Guitar Hero—Oasis Addition" a try.
