What kind of info are you looking for? I know a decent amount about horse racing.
The ponies are great if you don't want to gamble with too much money, but still want to have fun. The minimum bets are small, so you can spend way less than $200 and make tons of bets all day long.
I don't know your level of experience, but generally take a look at the website for the track. They should have a list of winning jockeys, horses, and trainers (all time and for just this season, maybe last season). Check it out, remember the top 5-10 in each enough to recognize their names again. Buy a Daily Racing Form, not just the little guide. Read the commentary by the handicappers for the day, look at the horses stats. The best money is usually made on Exacta's and Trifecta's. Don't bother with Quinella's, the pot isn't as big, just do an Exacta Box as the Exacta pot is nearly always higher.
I could go on and on about horse racing, lemme know what you're looking for.
