You may not have a snowmobile in the preserve. Nor may you have any alcohol. Nor an ATV. All dogs must be leashed. And, obviously, a hiker may only wear one shoe.
P.A. Nehring Forest Preserve, DeKalb County, Illinois
Diddle diddle dumpling, my son John
Went to bed with his britches on.
One shoe off, and one shoe on;
Diddle diddle dumpling, my son John.
