I love reading about urban legends.
Not "urban" so much, but basically local folktales.
During the Revolutionary war, an arms depot was hidden in northwestern Harford county, either in a spring house, root cellar etc. Never been found.
Supposedly, Bigfoot has been sighted in Harford County MD, and southern York county PA. Of course, the area in southern PA is a noted drug growing area, that might have something to do with it.
Last but not least, in relation to the Bunny man, I have heard stories about the Beltsville research center, and read about in the book Weird MD. Supposedly, the urban legend is that they are doing human/animal hybridization cloning there. Outside of the genre, I have heard all kinds of urban legends about the center on different "sports talk etc" stations coming out of DC.
