Not sure if it will apply to your son or not but want to let you know so you can research as much as possible before your trip. Would really suck to get up here and learn of restrictions then. Here youth between the ages of 12-15 have to share a firearm with their mentor, youth between 15-18 must be at arms length if they do not posses a miners permit but can have there own firearm. After 18 they must have a valiid PAL to hunt on their own. Like I said not sure if it will apply to your son if he is fully licensed for your area. Just curious, can he have his own firearm in Indiana with his valid hunters education card???
