BETUS has a Triple Crown prop....Big Brown wins Triple Crown (-160). He does not (+120). Interesting.
Also, they have the "Preakness w/o Big Brown"....for example Racecar Rapsody is 16-1 and you get 16-1 if RR wins OR places. Of course if you think he's going to beat B.Brown, a straight "win" bet should pay more than 16-1 if the odds hold up.
