Went to a Jets game this week because I had free tickets (still no reason to go but...). I think someone could do a gr8 social documentary on people who tailgate every home game for their football team. Getting up at 7AM and driving to a game, spending huge amounts of money on food/booze/flags/football paraphernalia. You go to the same spot every week, hanging out with the same crew who you have become friends with only from parking next to them every week for x number of years. Probably invite these people to their weddings, etc.
