You obviously know how to get on the G&F site to buy PPs, so all you need to do is go to the Draw Odds Section to find what you want to know. Units 37 and 41 A/O will probably draw with your 4 PPs next year. The other BigHorn Units will take at least 7 PPs next year for a 100% draw on that A/O tag. That's the stats for the Regular PP Draw. You can look up the higher priced Special Draw odds yourself in case you want to up your chances to draw, but you'll have to spend over $1000 just for the tag alone. There are deer thorughout all the BigHorns units, but it's not easy hunting them.
