Very interesting indeed. Not sure when I'll ever get over this way from WI, but wanted the CO to know it was being talked about many miles away. I saw someone mention this in the WGA forums, and being a puzzle lover I had to take a look. It took a bit along with a little collaboration, but I finally got it. I had part of the idea and another cacher had part of the idea and together the solve was made. Well done on a puzzle style I've never seen before.
