At least half of the fun that comes with going to a live football game (or, in some cases, a baseball game/basketball game/hockey game) is the promise of tailgating.
Tailgating is the way in which we lure our non-sports loving friends to sporting events. Who can turn down the promise of free food, ridiculous shenanigans of fellow fans and, of course, lots and lots of beer? The fall leaves, the smell of the grill, the antics of inebriated frat boys—it's the best thing about football season, by far.
For those of us who enjoy games, tailgating makes the day even better; for those who don't, tailgating gives them a reason to actually attend.
Of course, there are those fans who go a little bit overboard with their tailgating. If they want to invest that kind of time, energy and money into having the most epic spot, fine…but that doesn't mean you aren't going to get ridiculed.
