A few weeks back, we unsuccessfully searched for a geocache entitled "Are You Smarter Than a 5th Grader?" Today, we found it. It was a cold and breezy day, and we needed to keep moving. After over an hour of following clues from one intermediate cache to the next, we were ready to stop and come back another time to finish it. One last look on our way back to the car turned up the final cache, after about 2 miles of walking total.
