Not so much at this Gettysburg level, but one of the challenges for volunteer docents is that visitors often volunteer what I call "lore" that is based in myth, folklore, fiction, or folk etymology, and the docent, not having enough time to accurately correct the misinformation, is faced with saying nothing, or "I've heard that too." and moving the tour along. Lore at the level of: "spices can conceal the taste of spoiled meat" and "window glass moves over time, making panes thicker at the bottom." Later, other visitors will defend their misinformation with "Well, someone at <site> said it, so it must be true." Glad to see that NPS has serious standards.
