I'm just not one that gets very into the school spirit stuff. I didn't go to many athletic games for my High School after I got out of band, and didn't attend any at all for undergraduate.
I've actually considered showing up for the first week of classes in my Nebraska t-shirts. I went to High School in Nebraska, so started liking the football team at that point. Since my parents still live there, I get a Nebraska t-shirt or sweatshirt nearly every year for Christmas.
A couple years ago, I actually got to see my first Nebraska football game in person. It was here at UT, as some friends had some extra tickets. They picked us up wearing their burnt orange, and my wife and I were in our Nebraska reds. Luckily, there were some other Nebraska fans living in Texas, so we weren't the only red shirts in the sea of orange.
