Honestly? I haven't been to a game in over 10 years. A combination of expense and time. It's weird. I'm about as big a Cowboys fan as you could find and I live in Dallas, but I just watch them on TV.
This kind of job, really, is just like any other. The first little while it can do a job on the nerves, but you get used to it and it becomes second nature in a way. You can't always predict what's coming and occasionally you'll run into something you haven't heard before or someone will be so emotional talking to you, that you can't help but get worked up, but really, you get used to it.
