Should be a very good area - Central Missouri has substantially more agricultural activitythan the southern regions of the state; that typically meansgood numbersof big, i.e. well-fed deer. We hunt in adjacent counties, and have taken a number of mature 210lb+ (field dressed) bucks.

You're lucky also in the sense that you are on the border of the antler restricted counties (which require 4 pts on one side), which include counties adjacent to, but not including Saline.
Good luck this Fall!
