I've gone to a few sports memorabilia shows, but have never stood in line to meet any of the athletes or get an autograph/photo.
The only paranormal related event I've attended was the "Little Green Men" festival a few years back in Hopkinsville, KY. A bunch of yokels with more fingers than teeth, idiots in alien costumes, and a couple dilapidated carnival rides. Not a whoopty doo good time.
In March, a group of us will be attending this festival. It's literally ten minutes from my daughter's. Now if I can only find some mescaline. (Hunter Thompson fans will get the joke.)

I have spoken to more than a dozen TV/movie stars from days gone by on a radio talk show I listen to out of Boston every Saturday night. David McCallum, Barbara Feldon, Ruta Lee, Mark Goddard, Tony Dow, June Lockhart, Jon Provost, etc. They are usually promoting a book or some memorabilia show in New England, but McCallum and Feldon are regular guests.
