No goodies, no scenery, just a little history and a chance to log a find if you’re in the area. Please use care when parking, pull all the way off the road onto the narrow shoulder.
Verification question: What does the P. stand for? Email me the answer when you log your find. Don't post the answer (or a picture of the cache) here even if encrypted. If you can’t tell from your field visit; the answer can be found at WI historical Society, but take notes in the field so you know what to look for.
If you can’t find it , let me know and I’ll send you a more specific hint, and maybe another question to go with it!
