When Mama CatLemur was a small child, she used to see signs advertising Xings everywhere, but she never knew what a Xing was. She tried asking her parents, but when she did they laughed so hard they just couldn't answer her. There seemed to be all sorts of species of Xings, such as RR Xings, Deer Xings, and Ped Xings.
These days, it's harder to spot a Xing advertisement in the wild. It seems now there are signs with pictures of people, animals, or mechanical devices on them in the places where the Xing ads used to be. Every once in a while, though, you'll spot one...
This one is the only Xing advertisement in a parking lot full of the newer pictorial signs. The cache is not on the ad, which is listed as a Waypoint. Instead, it is located across the street from the establishment housing the Xing advertisement.
