I used to bet on the internet long ago.... then a law was passed that if your bank is based in certain states (utah being one of them) then you can no longer do it on the www. I was doing pretty good too.
Also, I hate betting on my favorite team. If they lose then you lose money and you are upset that your team lost.
If you bet on the opponent then you win no matter what.
Jazz lose, i win money. Cool
Jazz win, I lose money, but the jazz won. Cool
Hedging your level of disappointment. I like it!
