This story on CNN demostrates why you need to clearly mark a geocache as such. From the article, “In June, a bomb squad in De Pere, Wisconsin, used a robot-mounted shotgun to blast the lid off a suspicious-looking military ammunition box found in a park. It also turned out to be a geocache.” It’s a little bit funny, but also a tad scary. So paint a big red ‘geocache’ on your geocache boxes!
