I haven't yet but I enter a lot of radio contest so maybe one day I will. Then if I have up to a year to cash my giant check I'II hang on to it and take a bunch of photos, Like me and the giant check spooning on the couch, me and the giant check sitting at the breakfast table eating bowls of Loonies (Canadian $1 coins) and on days that weren't windy me and the giant check at the beach. Cheers!
