I like to tailgate party.
In New Orleans, We have tailgate parties in the Parking Lot of the Superdome. 
We mostly do college football tailgating.
Tailgating come in all forms.  We bring the bbq, some bring rv's & campers !  But the orgin of tailgating is held on/near the tailgate of an automobile
Sometimes we don't even make it into the stadium.
That is true ! I see some people bring their own poison (beer, liquor, etc) to make the event 'sociable'.. More time is spent in celebrating before the game instead of After the win !
