Rainwater retention ponds abound in our area. Many look like city parks. The original container was a 3-D printed one. As was the case with most of my 3-D printed caches, this one "disappeared". So I replaced it with a 4 inch PVC tube in the ground nearby and reset the coordinates. The tube looks like it belongs there, but it is a geocache container. Remove the rubber cap, unscrew the wingnut, and open it up. Log and pen are in a tin holder inside. Please replace both caps and tighten the wingnut, as this is necessary to keep the inside nice and dry.
