The earlier the scrape the bigger the buck will be in most cases. Yearlings and 2.5 year olds are still getting used to the raging hormones come this time of the year and don't start scraping until Mid to late Oct. most the time. If you find scrapes now get excited. But don't put too much time in hunting over them. I wouldn't move my stand any closer, if anything I would try to find a trail or a buck bedding area and hunt closer to that or the trail(s) leading to the scrape. Even if that means moving away from the scrape. I love seeing scrapes and my gut instinct still tells me to set up on them, but i don't because as Goose said 85-90% of scrapes are visited at night. It wouldn't hurt putting your trail cam there. That's a good move just to see what you got out there. Use those pictures to try to figure where the buck is coming from/going to. Once you figure that out, you need to be hunting that trail he is taking, esp. if he is on it constantly. Another note on that, if you find that the scrape is facing east or west that will help tell you when he is coming to look at it, more towards night, or early in the morning. Good luck!
Them Darned ol' deer.
