So, like anyone who knows anything about Groening and the Simpsons saw it coming, Springfield is based off of Springfield, Oregon and, of course, Portland, his hometown. It's not like this was a big reveal, but it's nice he finally came out about it.
















"Everything you can experience in Los Angeles, you can have a much better version of in Portland -- including, very basically, the air you breathe." - Matt Groening
