PHILADELPHIA (Wireless Flash) Do you believe in elves? Well, theres a Philadelphia man who actually claims to be an elf. 29-year-old Tirl Windtree runs a community support website for otherkin people who think they are really some sort of creature thats not fully human. Some otherkin believe they are vampires, dragons or elves and some even feel the presence of phantom wings and tails. Although many otherkin are in the closet about their true identity, Windtree says a few live together in family homes where they can be open about their unusual identities. He estimates there are a few hundred otherkin communicating with each other online, including his website, Otherkin.net.
