I like the actual substance of the story how the guy used his Six Flags park pass to take advantage of his situation. Did he eat the best meals for a year? Probably not, but good thinking on his part.
We don't have Six Flags here, but Cedar Fair (Kings Island) and they offer pretty much the same deal for $145 - drinks are not included. So you could in theory drink the complementary water in the park and spend $145 for 6-7 months of food (2 meals, 4 hours apart). For the drink, you can buy their souvenir bottle for unlimited soda which is $35. If I were single, struggling to pay off debt or didn't give a flip what I was shoveling into my mouth and lived close to the park, this would be a hell of a setup!
