What stage of the rut are your deer in? Once you see the first breeding forget the scrapes and rub lines, if they visit it will only or more than likely only be at night. If there still pre rutting as your just now finding your first scrapes and rubs and their all still very fresh, then hunt em.
Hunt it the next day after you find it and hunt mid day, say about 8 till 3, its a tough sit but chances are best he'll show up about mid morning 9.30 ish or between 12 pm and 2 pm.
Scapes have been more productive for me than rubs unless its rub line where numerous rubs can be found generally in a line and some scrapes mixed in along the way, pay attention to see if the scrape has a licking branch over it where the buck can actually rub his forehead and face and lick some branches. If this is the case and they have not actually begun chasing yet, hunt it.
If the rut has started go to that area where the rubline and scrapes is at and put out about four wicks or cotton balls are whatever with tinks placed them about 10 yards apart in a line where the wind say blowing from the north will blow it down through the area where the rubs/scrapes are, then back off and hang your stand about 80 to 100 yards south and about 30 to 50 yards to the east depending on how thick the woods are and how far you can see. This way you can ambush him as he comes in and you should be ok with the wind, because he is going to come in from downwind so you have to be off the side and back to catch him sneaking.
That has been my experience at least.
