Legend tripping and Tam Lin

I have been working on my research for my new manuscript on the topic of legend tripping. A google search on the term resulted in an entry from Wikipedia which was of double interest to me as it incorporates two of my fascinations-- contemporary legends and ballads. The entry begins:

Legend tripping, also known as ostension,^[1] is a name recently bestowed by folklorists and anthropologists on an adolescent practice (containing elements of a rite of passage) in which a usually furtive nocturnal pilgrimage is made to a site which is alleged to have been the scene of some tragic, horrific, and possibly supernatural event or haunting. The practice has been documented most thoroughly to date in the United States.

It then continues...

Much older versions of the custom may be glimpsed in traditional ballad tales such as the ballad of Tam Lin. In this ballad, a young woman is warned that the elf Tam Lin is known to haunt a place called Carterhaugh, and that all who go there must lose either an article of clothing or their virginity to Tam Lin. Janet, the heroine, defies the warning: she goes to Carterhaugh, picks a rose, encounters Tam Lin, and becomes pregnant with his child. She learns that Tam Lin was once human, and that to free him, she must make a second trip on Halloween night to a crossroads, where she has an encounter with the Queen of Elphame, and succeeds in reclaiming Tam Lin from fairyland.
In both the old ballad and in Mark Twain's version, there is a specific location that is supposed to be accursed, ghost-haunted, or otherwise dangerous. There is a folk story, of the type that is now called an urban legend, that explains why the place is haunted, accursed, or dangerous. The story is retold in preparation for the legend trip. In outward form, the legend is a cautionary tale warning of a danger; in practice, however, the cautionary tale is turned into a dare, inviting the trippers to go test its veracity. There is sometimes a ritual that must be performed at the site, the ritual is explained in the legend. The ritual invokes whatever dangerous spirits haunt that place.
