Tim Horton's 'Roll Up The Rim To Win' Contest is really a huge part of what it means to be a Canadian. The contest is inextricably woven into our cultural fabric. We love it. I more than double my daily Tim Hortons consumption when the contest rolls around just so that I can get a chance to win a free coffee or, should I be so lucky, $10,000 or a new car. So far I've only won the coffee, but that doesn't mean I have given up hope.
