According to legend, the term muggle came to us from JK Rowling and her “Harry Potter” series. In the world of Harry Potter, muggles are ordinary people who are unaware of the magical world around them. The same holds true of muggles in the geocaching world: muggles are unaware of the treasures surrounding them – geocaches.
Urban geocachers remain particularly aware of muggles. The goal of the urban geocacher is to blend in without raising the prurient interest of the general population. In their innocent curiosity, muggles may muggle, or destroy, a cache.
However, many urban geocaches are hidden well within the view of muggles. One of my early finds is on the sign of an oil and lube at a busy intersection.
