On my break from a conference in DC today, I walked to a virtual geocache that required me to walk a labyrinth carved into the ground and follow a very specific set of instructions.
Right as you enter the labyrinth, you'll notice the only place where the lines of the labyrinth cross. As you round the labyrinth, keep track of how many times you go past that point on the way to the center. (In other words, if there was a line drawn on the ground from that point to the southwest edge of the labyrinth, how many times would you cross that line on your journey to the center.)I wasn't sure I followed the instructions correctly, so I took a picture, came home and re-traced my steps. (I had.)
Then I noticed that the cache "owner" -- who is the only one who could prevent me from logging the cache due to a wrong answer -- hasn't logged on in a year. So I didn't really need to do this. So it doesn't go to waste, I share it with you here.
