Hot Dog 1 : The ones that the vendors sell in the seats for $2.50 in the silver packet. Steamy goodness!
Hot Dog 2 : The "grilled" ones that hang out with the bratwursts and smokies, available at the concession stands such as "Doggy's Dogs" et al. These babies will set you back $3.75!
Now, why can't you buy a $2.50 hot dog at the concession stands? Why do I have to wait for the hot dog cuties to come around and sell me their wares from the red foam Kahn's bags? They never seem to be there when I am craving the pink tastiness...
And really, what is so special about the $3.75 dogs except that they are negligibly larger (debatable) and slightly browner (sometimes)? They taste pretty much the same to me... not enough to justify the price difference methinks.
Plus I like the steamed ones better anyway! Three of those dogs will set you back the same as two of the high-falutin "grilled" dogs and will fill yer belly a lot better for $7.50!
Inquiring minds want to know. And yes, I have thought about this too much.
