This was a plum job for us growing up a couple of miles north of The Stadium. See a game, get a tan, make some cash money.
The upper tier is trecherously steep but the fans tend to be alot more 'animated' and better tippers than the suits in the corporate boxes with the comped tix.
Sellimng hotdogs is the worst of the vendor jobs.
Hot, heavy, bad tippers (compared to beer)
