I was out geocaching with Jeff and Marla yesterday, and we searched for one of their caches. In the second stage, we were required to do some arithmetic to generate the final coordinates, and trekked off along a path.
When we arrived at the location, there was a fallen tree, and Jeff proclaimed "Hey, that's not right!". Digging around in the broken remnants, Jeff extracted the cache. It was a black
PVC ABS container, but for some strange reason, it appeared bright orange. On one side. It turned out to be covered in a bright orange and bubbly mold.
