I don't really know any chick that would just love to have her marriage proposal made around any kind of sporting event.
The last Bama game in Fayetteville that Petrino coached, the one we were all really hyped for, my wife(girlfriend at the time) and some of her friends wanted to have a tailgate. I went all out and got the whole thing organized. I'm usually pretty laid back but I wanted this to happen so I really took charge and organized the whole thing which I guess was unusual for me. I had also talked to our buddy who does some camera work and tried to get him to come video us for the tailgate of the day or whatever they call it, since our tailgate also included a guy that was sitting with Jeff Long for that game and I think leading the hog call at the third quarter or something like that. That camera part didn't work out, but they knew it was a possibility.
Later on, I found out that my wife and her friends were all surprised at how I took charge of it, and were convinced I was organizing it all so that the camera would be there and I could propose to her on the big screen. So the whole tailgate and the whole game, she was expecting a camera to show up and for me to propose in front of everyone.
I say all that to say, she was pretty disappointed. It sounded like a great plan to me but I never thought she would have gone for it. Once we got engaged we ended up talking about it and she told me how she and her friends thought I was proposing that day, and I told her I wouldn't do that to her. She told me she would have liked it, because our relationship pretty much started with a trip to california to see the hogs play USC.
So it depends on the girl, but mine actually expected me to propose at a hogs game and would have liked it.
