Well Kadron, there is a lot to know. First off, I am not an alum, but am related to three, and may be a future alum. All I can tell you is that they take the utmost pride in their alma mater, and will always support whether they are 3-9 or 13-0. Secondly, a degree from Notre Dame can get you a job anywhere in the world, it is a very prestigious degree and you are getting a top education. I know valedictorians of their class who were rejected from ND, thats how competitive it is. Not saying you can't get the same great education at other schools, but it is guarenteed at ND.
Game day wise, it is just a special place. There is just that aura in the air. It might not be the loudest stadium, but it sure is special.
South Bend, Indiana might not sound like the most liveliest city in the world, but there are plenty of clubs, you are close to the great lakes, and there is plenty to do.
