This afternoon's excursion was to Saddle River Puzzle, which was in a small park in the nearby town of Saddle River. The puzzle part was to reassemble a bunch of rectangular pieces to form an image with the coordinates. I was going to print and cut out the pieces and reassemble them by hand, but I realized that it would be too much work. So I did the puzzle in Paint.NET.
Once I had the answer, the park was a mere 2 miles away and the cache site was a quick walk around the pond to the banks of the Saddle River.
