An elderly Arizona man is doing fine despite riding along a busy freeway in a golf cart. Troopers say it's not exactly clear why the 83-year-old was on Interstate-10 in the dark of night last week in the Phoenix area without the lights on but the guy is very lucky he wasn't hurt or killed. There is video online of the incident that shows cars speeding by while the cart rolls along without any headlights. They also say it did not appear the guy was drunk or under the influence of anything. His wife was contacted and took him home.
