My favorite "Mitty" story concerns a guy who had a classic Porsche or Lotus. (I forget which.) This was back when I used to work corners at Road Atlanta.
Told his wife that he was going to the Mitty to play. She begged him not to, afraid that he was going to wreck his car.
He said, "Okay... I'll just go play golf, instead." ...and came to the Mitty anyway.
Long story short... he lost it on turn eleven, went off to the left, hit a small rise that was in the grass/dirt, sailed right over the Armco (guardrail) and ended up on his roof, in the woods. He wasn't injured. The car was another story.
