I bowhunt in Brown county Illinois every year, and love it . The area I bowhunt the terrain can vary up to 350 feet , makes for ridge tops , ridges, and nice valley's a very nice looking area, with plenty of ag crop fields, CRP fields and food plots. The deer #'s are excellent and I see plenty of big bucks and big does, I see plenty of pope & young and Booners coming out of Brown County. I would suggest if you have the oppuortunity to hunt there dont pass it up
