hunting mock scrapes. how many of you hunt mock scrapes? I have never set one up and thought about trying one this year. How long does it have to be up to work can I use it on a 4 day hunt or does it have to set up longer than that to have deer come into it. I was planning on using it when I went to SD this week but if it is going to take a while for deer to start coming in to it then I will just set it up here before I leave and hunt it when I get back any advice would be great thanks
