I'd like to know what distinguishes a "real buckeye fan" from a phony. To me it sounds as if the logo on the tent is what this OP is claiming makes you "real" or not. I can imagine there are plenty of "real buckeye fans" affiliated with these corporations who sponsor the tailgate (pay for the food, tent, parking pass, beer, etc.) for the opportunity to advertise and promote/create good relationships with FANS tailgating.
For one, my dads best friend has been putting on his tailgate for years (and I've enjoyed helping him with the difficult tasks that come along with throwing a good TG every home game), his recent move to Huntington has provided an opportunity for the corporation to have a place for Columbus employee's, families, and friends (most "real buckeye fans") to tailgate and use his "free" labor in setting up, tearing down, purchasing, and hauling everything needed that we provide, while they throw up a tent with "Huntington" across the boarder. Meanwhile, the cost of putting on the tailgate is now completely paid for by Huntington, and nothing has changed.
Also, how can the color/logo on the tent take away from the atmosphere? Unless you're looking from a birds-eye view, the only thing that affects the atmosphere are the people.. If anything, adding the corporate sponsorship has brought more people to our tailgate.. The only reason you see more corporate tents closer to the stadium is due to the cost behind the parking pass in the prime areas. It's often just too much for the average "fan" to take on without corporate dollars. Such is the real world.
I'm all for idea's to improve the atmosphere though.. GO BUCKS!
