Try this if you get the chance. If you have two hunting spots 3-5 miles distant from one another, find an active scrape and in the AM collect a double hand full of dirt from one. Be very careful no to contaminate the sample your going to collect and put it into a scrape 3-5 miles away. This can be extremely effective. The best way, at least for me to collect the dirt is newspaper and a stick. Make a cone out of the newspaper, holding the cone by the pointy end use about a 2 foot stick that you found nearby, push the dirt into it and fold up the newspaper. Secure with a rubber band. When you get to your other active scrape in the afternoon just unfold and dump in. You could be in for a pretty interesting evening hunt. I've seen bucks come into the scrape with fire in their eyes and the hair on their back standing straight up and snorting with every step and proceed to tear up the surrounding area. I've seen other bucks come into the scrape, lay down like a dog and roll around in it. I've seen other bucks come in on tippy toes and walk way around the scrape with their tail tucked tight to their butts, sometimes I've not seen a buck. Your milage may very, but it's worth a try.
