You need to register for the lottery on the IN DNR website and be chosen. Log onto your DNR account and look for 'Enter a Reserved Hunt Drawing" on the right side of the site. From there follow the prompts. It now costs $1 to enter. And apparently they will now start a point system for people like me who should have 30+ points and those with the most get preference since they haven't been picked. But I'll believe it when I see it.
I have registered nearly 30 times (or more) and never been picked. Have had friends picked multiple times in that period, however and each time I have been invited have seen at least 50 pheasants except for one time. Went last year near Earl Park and saw about 70.
