I know that Weds night, I'm going to the Olreans (since they are open all night and I don't land till after 7:30 pm) to put in my bets for Thursday . In the past March madness visits, I've noticed that they have "Half point" paraay crds, "ties win" parlay cards and "teasar " parlay cards. I imagine ( and I could be wrong) that you can place these same bets over the counter by just telling the bookie ( guy taking bets at the sportsbook) what you want. What, if anything, is the advanctage of using the "cards" for these bets?? T- 3 days till VEGAS!!!!
