RE: What have you done?
If I ever shoot a buck in Illinois, it will be one that I am proud of and that I have earned through hard work, hours on the stand, perserverance, and passing up the bucks that just don't make for the total experience. I will be proud of it. No one else needs to be. And that would be 'what I have done'.
I go to Illinois (this year will be my third year):
1) Because I wanted a hunting vacation, away from places I normally go and away from the 3 month rifle season and highly pressured deer you typically get in GA.
2) Illinois is a great place for archery hunters and to have an opportunity at quality animals.
3) I have a great group of friends that makes the experience ever better.
4) I have great DIY property. I prefer that, but would use a guide if it were required or necessary.
5) I am a whitetail addict. Elk, mule deer, bear, etc. just doesn't do it for me.
6) It's a close enough drive from GA that I can take all my gear with me and do some year-round scouting.
