I didn't check their arbitrary rules. There was a relatively late scratch, but it happened well before I placed my wager, which they obviously accepted. When there's a sports dispute they will abide by the score of NFL.com, NBA.com, NHL.com, and so on. But in horse racing they won't abide by the track in question. That, to me, is the bottom line. They're good enough at sports, but they really are terrible at horse racing. Unless you don't mind races being taken off the board five minutes before they go off.
