When it's reasonably convenient, I enjoy the challenge of the side game in geocaching of First to Find. As a result, I have my preferences set up to send me an email notification whenever a new geocache is published in the surrounding area.
Last week I got a notification in the evening of a new puzzle cache titled Johnny B. Goode. Just as I was looking at it, I got a message from the cache owner, "One with you in mind!" Obviously, this was one that I needed to review closely! I was able to solve the puzzle to get the actual coordinates relatively easily, and then started reviewing that location in Google Earth. While I really enjoy hiking around in the desert at night, this location was one that I didn't want to do in the dark.
