I recently purchased a farm close to my home and will be able to get out to it frequently. I'd like to try and make some mock scraps this year around some of my stand locations. I was wondering if anyone had some advice for me...i.e.- How often should I check on the scrap? Do I need to purchase a drip bag and hang it above the scrap? Is this even an effective tool for hunting or does it put to much of my scent in an area? How successful are they? Should I do more than one in a small area? Really any advice would be great!!!! Thanks in advance!
