Zion, the town just to the north of Waukegan, has a very unusual history having been founded as a religious nut that outlawed all kinds of sinning.
This is just one of the hilariously belligerent signs placed at every route leading to the city. I think this is on the route from Waukegan on Sheridan road.
More signs - even more belligerent signs - can be found at the
Zion Public Library's website.
