"Rubber meets the Road"

This is another shot from geocaching the other day. For anyone unfamiliar with geocaching, the basic premise is that someone hides a container of some sort somewhere... anywhere. In this case the container was hidden off of a walking trail in a little park. They post the coordinates of where it is hidden at geocaching.com. Others then visit the website, get the coordinates of the cache, and use a GPS to help them find the container out in the middle of nowhere. This particular cache was a multi-part cache, so it had a few different clues along the way before the final location. One clue was about "where the rubber meets the road" and the clue (the next set of coordinates) was actually written on the bottom of this tire swing in white lettering. When I first took the picture, I didn't realize it would be the clue.. I just thought it was a neat picture. The shot is straight from the camera.. well, resized.
