Every year I make a wager on the MLB All Star game on the National League. Usually I am in LV either the week of or before the game when they always will have a line. This year, I will not be. I was going to speak to a sportsbook manager and find out if I can leave money with him, when the line is put on the board have the wager placed, and the money sent to me if I won. Are there any other options?
