RE: ILLINOIS residents...Someone told me its illegal
Yep. illegal. It used to be OK to put out salt/co-cain/etc. as long as it was removed 10 days prior to the opener. But now it is 100% illegal to use any bait(including feeders)for deer, anywhere, even if only for photography or recreational viewing. Keeps deer from trading spit; it's a health issue, not a 'easier hunting' issue. Funny how you can still buy bait in most any sporting goods department...
Not sure on the food plots or fields, though.
And this isn't anything new, it's been law for 3-4 years.
