"There was a crooked man," by Mother Goose
There was a crooked man, and he walked a crooked mile,
He found a crooked sixpence against a crooked stile;
He bought a crooked cat which caught a crooked mouse,
And they all lived together in a little crooked house.
You won't have to walk a mile along this crooked fence to find this cache. No sixpence in there, but maybe a little space to leave a token or two. The path runs outside the western edge of the Heckrodt Wetland Preserve in Menasha.
Snowfall may make this one a little more difficult in the winter.
