They put the salt blocks right at the water. The pond on the same property 2 miles away a lot of dead deer . The deer in this area only a few . Multiple game cameras and people watching. Did it really make a difference tough to tell on such a small sample but if it works you would think gfp would be open to trying the garlic salt licksSince EHD tends to make the deer thirsty, can't say I'm surprised that there weren't too many dead deer found near the salt blocks. Last thing most of us want when thirsty is a salt block.
