Governor Pat Quinn recently signed legislation allowing expanded use of crossbows during the Illinois archery deer and fall archery wild turkey hunting seasons. A legally permitted archery hunter may use a crossbow from the second Monday following Thanksgiving through the end of the archery hunting seasons. For the upcoming season, those dates are Dec. 3, 2012 through Jan. 20, 2013. Illinois law continues to allow use of a crossbow throughout the entire archery season by persons age 62 or older and handicapped persons who are issued crossbow permits by the IDNR.
