Hey Jeff - following/adding to the discussions and having your profile to 100% is the best way to score some really cool swag.  I've not actually seen the bumper stickers, but towels, bag tags, hats, TT stickers and lanyards are among the stuff that can come from out of the blue for being a loyal follower.  I have purchased my own license cover of "I'd rather be driving a Titleist".  Good luck and stay active.
