I recorded and watched the six "Halloween" movies AMC had on TV during the week of Halloween.
When I got to the sixth movie "Halloween 6: The Curse of Michael Myers" I had to back the VHS up when I saw a map of the Haddonfield area. It was what I thought it was. There was a map at the bus station showing Haddonfield and its surrounding towns. To one side was Dwight and the other was Pontiac. I also saw Joliet and Gardner nearby.
That would be nowhere else but Illinois' Livingston County.
Haddonfield would be about where Odell is.
That means, Route 66!!! I didn't know that. I'd always figured the town was somewhere south of Springfield.
