RE: Nov 1st-7th in Illinois
I hunted hard last year and we had one of the best ruts we've had in a long, long time and the biggest buck I saw might have pushed 150". It's been a few years since I've layed my eyes on a 165" deer in the wild, hunting or not. They're definitely here, but there certainly not as easy so spot and to hunt as a lof of tv shows and hunting videos might lead you to believe. It still comes down to the area you're hunting (if there isn't a 165 living there, you ain't gonna see one!), the weather, and of course your skill and knowledge as a hunter. If it all plays out right you just might get a shot at a monster, but you'll have to be both good and lucky.
Good luck during your trip, I look forward to hearing how it turns out!
