How do you get something autographed by Wayne Gretzky?

Hockey players will regularly hold public signings, check your favourite teams website for more information. Another option is after games there is usually a gate in the stadium from which all the players will exit. It takes sometime but if you wait after the game a number of players will stop to sign. As well if the team is going on a road trip (or returning) they often sign Autographs at the airport. Any other options will most likely result in a restraining order.
