I live in what they call the (Grape Belt) our area has thousands of acres of Grapes, it's mostly a Agricultural Community, Farms, Cattle ect. Plus there's an abundance of Natural Gas underground so there's also Hundreds of Gas Wells. Next to the wells there's a (Brine Tank) salt, the Deer love these spots. We also put out the Mineral Lick's (brown) and salt blocks, they do attract deer but there's so many other options for them that it's a hit and miss with them with all the crop fields, corn, soy beans, pumpkins, cabbage, ect. Plus all the apples trees and acorns it's a never ending smorgasbourg for the deer. If you really want to attract deer, plant apple trees, it takes awhile for them to mature, but once established you'll have deer comming to them all fall and winter. In our state it's considered (baiting) if we use salt blocks. The one's we put out are there just to help the deer, we never hunt them. But with all our natural crops around, that's where we set up. It's funny that you cant bait say with apples, but you can hunt apple orchards and all the other crop fields.
