I live in west virginia ,where they have slot machines in bars. The state lottery is advertised so much and in so many different ways you want to shoot yourself. In Charles Town, we have a racetrack where you can bet on live horse racing, as well as tracks across the country. Next to the track there is a "casino" where they have literally five thousand slot machines. You can legally wager on fucking dog races.
Betting in card games, however, is illegal.
