well, for mine, it was easy for several reasons - started her with Uncle Scrooge and Scooby-doo, she was already hooked on Scooby-Doo on TV, and we all got to Science Fiction conventions, so she has grown up Fandom (she's 17). I have lost track of how many Cons she has been to (in four different States)m and I have no clue how many I have been to (couple of hundred over the years).
