I think the tailgating movement will die a natural, evolutionary death when we build a state of the art domed stadium with opening roof in downtown Buffalo.
Seating capacity will be reduced, ticket prices will go through the roof, Russ Brandon will heavily target corporate southern Ontario/TO for ticket/suite sales, there will be inadequate parking in the area, and the demographic attending games will change dramatically.
The folks who currently use a Bills football game as an excuse to get **** faced drunk and let off some steam will be forced to find new pursuits.
Soon thereafter, older Bills fans will be telling the young ones about the good old days of tailgating out in Orchard Park.
I grew up with stories of the old Rockpile, even though that stadium was really before my time...
No one now is really lamenting the loss of War Memorial and it will be the same, given the passage of time, with Rich Stadium, or whatever the marketing department is currently calling it.
