Springfield is not a real place- it is largely based on the area near Springfield, OR where Matt Groening grew up, and he chose the name because so many states have Springfield's. On the topic of Simpsons products in 7-11's, I tried a pink frosted donut yesterday. It is the real life version of the kind that Homer eats on the show. It was terrific, but didn't feel too good in my stomach after mile 8.
