In the back of a used bookstore, Loren Coleman displays his extensive collection of model 'cryptids' – animals thought by mainstream science to, er, not really exist.

Coleman, who's been a consultant on dozens of monster-related TV shows, is happy to answer even the weirdest questions. Get a picture with the 9ft-tall bigfoot on the way out.
