I put 2 of them out this past Monday, I hung them over mock scrapes that I made that day at the same time that I hung them up. I Hung one up, then made a mock scrape right under the dripper, put Active scrape in the dripper, and then dumped a little in the scrape. This was at 3:50 PM. I got in my stand and had 3 does and an 8 pointer check it out at 4:05. They didnt paw at the scrape, but they did sniff all around it and the 8 pointer licked the licking branch that I made. At 4:10, I arrowed that buck at 15 yards. I dont think the scrape is what brought them in, I think they just happened to be in the area, and came up on it. But it sure was fun to watch.
