This cache was easy once I stopped trying to solve the puzzle. With winini's log and some perspective, I was able to figure out the location. Finally convinced my other half to go hunting for a cache that I didn't know the coordinates for tonight. We searched for about 10 minutes before we found it in a logical place.
Nice place to visit. It's a little strange to see these huge houses so close together with no trees between them.
Someday I hope to figure out what this cache means and how to solve the puzzle! Thanks.
