I agree that the blind should be put up for the deer to get "used" to it. But when I was in high school a friend and I left right after school on Fri. to go get ready to hunt on Sat., I know very late but we were young. We thought it would take the rest of the day light hours to set up to two spots to hunt from but when we were finished we still had hour and a half of shooting light. So we took all of the tools and left overs back to the truck and got dressed and hunted until dark. That night I saw more deer then any other day that season. Just my .02
