its always funny trying to describe horse racing bets and payoffs to people who dont understand it. They think you can win any amount of money on any given race. Like the earlier post says, there is a pool of money that was bet into that race, you can only win what money is in that pool. That being said, you will get a bigger payoff playing at a big track that gets lots of action.....like...belmont, santa anita, churchill...etc. So a trifecta with the same odds on the horses will pay much different at a bigger track than at a dump like Great Lakes Downs.
