I have over 5000 fast passes and not valid fast passes. My collection includes fast passes from all 11 Disney Parks, first day of fast pass, last day of fast pass, and many unusual fast passes. I also collect the many messages on not valid fast passes such as "you did not use this ticket to enter the park today", "you can not get a fast pass for Space Mountain, you already have a fast pass for Space Mountain", and "you can not get a fast pass today, today is not your birthday". My collection also includes Ghostwriters, override, blanks, inverted stock, double printings, misprintings, rider switch, and surprise fast passes.
