I purchased the Deer CoCAIN Black Magic at Sportsmans Warehouse for $7.99 a bag. All you do is find an area fairly secluded just off a trail they use, clear out an area about 4' in diameter, loosen up the dirt on topand sprinkle the powder on the ground. I had deer hitting it the evening I put it down and are still frequenting it. The deer find it by the smell I presume and then once they start licking it, they stick around for several minutes. It's pretty amazing stuff.
