One week in Los Angeles with my decrepit old father, who still insisted on sitting at the driver's seat in spite of being obviously unfit to drive. The times we almost crashed, ran over pedestrians or hit stationary objects were too numerous to recount. And when I was not having a heart seizure inside the car, we were wandering aimlessly inside every 99 cent and bargain store the old man could find.
I never went on another trip with him until he finally kicked the bucket.
