We tried to locate a cache on the 14th Street Bridge today. This was our second attempt. The first time we could not really look because there were too many people. Today, no people, but we still couldn't locate it. Because we are new at this, we really don't know what to look for. As part of the River Walk Geo Cache, we thought we were looking for similar cache boxes, but I guess that is not the case. I guess we will have to try again. Before we left, I took a shot with my iPhone.
