I'm lucky... in that my wife knew when we met that I made the trip to NCAAs (as well as either Scuffle or Midlands) every year. I've attended each national tourney from 2003-2019 - except 2009, when my daughter was born. And 2009 has its own story.
The first day of the tourney (March 19, 2009) happened to be the due date for our first child. Like many folks, I had bought tickets for that tourney nearly a year in advance. Wifey & I are at a pre-natal visit in early March and OB says, "Everything's looking really good here... I think we can induce on March 12th." My quick response was, "Oh great! That means I can do to..." I'll never forgot the immediate glare I got from my wife that stopped me mid-sentence. She didn't realize that I had already sold my tickets a couple months prior. I still joke about it from time to time, but she doesn't find the humor in it.
