I checked with one of my local CPO's here in IL and he said if it is salt or mineral based it is illegal!!...He also said the #1 way of deer spreading CWD is with siliva...If one deer licks the stuff then another comes and licks the same spot you just spread CWD to another deer...Since we already have CWD in Northern ILit probablywouldn't be good to use that stuff......This CPO recommended that in Sept. to plant wheat...He says they clobber that early in the season.....
