This isn't quite a "Fathers and Sons" trip, but last year I was invited to join my Father-In-Law and his friend on their annual trip to the mecca of motor-sports, the Indianapolis 500. While I am for the most part a NASCAR fan I have become attached to the spirit of auto racing in general, so I had a fantastic time.
Additionally, I am proud to say that I survived a flea-bag motel so bad that even the roaches didn't stay there, a thunderstorm that started while we were sitting atop a metal bleacher, and the hundreds of thousands of people who descend upon the Indianapolis Motor Speedway each year.
