CBB: If I recall correctly the odds for the non-resident Big Game Combo drawing are 50/50 or 50%.
Be sure when you apply in 2,011 to suffer the additional indignity of BUYING the "bonus point" option.
This allows that if you are unsuccessful in 2,011 then you will get a "bonus point" and your name will then be enetered TWICE in the 2,012 drawing. That gives you about a 75% to 80% chance of success there in 2,012.
Best of luck to you in the drawings and in your Hunt.
