I havea spot where I put down whitetail addiction, a mineral block, and a salt block. the $4.50 50 pound salt block gets the most pictures hands down. the whitetail addiction is in second place, but you have to refresh it every six months. I swear to god,I have more pictures of runaway cows at the mineral block then deer! For six days back in August there were 4 cows pooping all over my property and licking my mineral blocks. No deer ever touches them. go with salt (if it's LEGAL!!!). Corn will work much better but it's illegal in mn.
