As per my sister, we decided to go geocaching, too! One of Chris's old roommates got really into it for a time, and then we kind of forgot it existed. We checked the site and went out in search. It was really dark out already and we only had one flashlight between the two of us, so it took quite awhile. We had basically given up and were about to head home without finding the cache, but flashed the light over one more spot and found it! It was pure luck. Needless to say we only found one and then went home.
