At one time my main interest in sports was as a focus of my online gambling activities. Several years ago I received a promotional mailing from an online casino, indicating that if I opened an account, they would credit it with $100. The catch (isn't there always one!) was that I would have to win enough wagers to increase the balance to $1000 before they would send me the money. Fat chance of that! But, I decided to give it a shot, since I had nothing to lose. Long story short, through pure dumb luck I managed to build the balance to $1000, and they sent me a check!
