Wisconsin.
I was waiting for this one to come up, but because of zombies?
haha
The Texas Chainsaw Massacre, Psycho, The Silence of the Lambs: all influenced by the story of Ed Gein from Plainfield, Wisconsin.
There was a book written called Zombie based on the killings of Jeffrey Dahmer from Milwaukee, Wisconsin.
But then we have all the good reasons too, like That 70's Show, Laverne & Shirley, Happy Days, Step by Step, and The Young and the Restless.
