Long Creek Cemetery, Sunnyvale, TX
The President of a community cemetery association for Long Creek Cemetery in Sunnyvale, TX, wants everyone to know that letterbox "is against our rules." Furthermore—and this is a direct quote: "Please let your members know not to place their letterboxes in cemeteries. If we do find or witness geocaching on the grounds, law enforcement will be called, and that person will be trespassed."
