A pretty good list. Though my favorite thing is walking around a college campus on game day.

I would also say just the atmosphere of campus in general. As a student, it was so much fun going to games and being there with another 20,000 other students. All collectively drunk and cheering on our fellow students.

Our campus would cease to function on Saturdays. It was huge (Michigan State) and we have a very large alumni network, so tailgating would stretch out across the entire campus. Whatever lawn areas were exposed, were quickly overtaken by families, students, faculty. Not to mention the open container policy on campus ;)

Plus ya know, fall weather. Everyone loves fall weather.

Please add some more to the list in the comments.
