This is a four-stage cache, with the first three stages containing puzzles that you will need to solve in order to find the fourth cache. Please bring with you some paper and a writing implement, as you will need them. Please do not write on the puzzle sheets within the first three caches.
Unlike most puzzles caches I've seen, however, this is not a standard "calculate-the-coordinates" type cache. A calculator is not required. I created the puzzles based on my general knowledge, which, of course, may be different from your general knowledge. If you get particularly stumped by a puzzle, the nearby West Bend Library may or may not be useful: N 43° 25.253, W 88° 11.057. The address is 630 Poplar Street.
A note on the terrain difficulty: most of the terrain is probably only 2 1/2 stars, but there are a few brief locations where dexterity or a short climb are required. Hence, the four stars. Remember, the cache seeker assumes all risks of seeking.
Good luck and enjoy. If you get terribly stuck, I may (or may not) be convinced to help you along a little bit ;-).
