This happened to me Sunday morning.
I'd found a nice line of scrapes and followed the rub lines in between them until I found a fresh scrape, larger than the rest about 20 yards from the edge of a thicket on the downwind side. I trimmed my way about 20 yards further in figuring the buck would scent check his scrape from inside the cover in the daylight. Went and pulled a ladderstand and put it up in a red oak there. Sunday morning I went it to kill him and found that I was right, he did check it in the daylight on the downwind side but he checked it from 80 yards downwind!
He smelled me, tucked his tail and sneaked out of there back into the pines. If I hadn't seen him, I would have never known he was there.
