I will add , if you have a field cornering into timber and can catch the wind blowing INTO said corner and get there without being winded, you will most likely be sitting pretty.
The deer love to cut thru at the corner and the wind blowing into the trees will most often lift to go over the brush taking scent with it.
You need a hundred yards of timber or so to keep it up so it doesn't curl back over and right into the brush with you.
If you sit on the downwind side of timber(as I did for awhile) waiting for the deer to come to the open , they will most likely win, because the wind will curl right over , down and back in with them.
Get some milkweed fluff, it's free , not noxious weed, butterflies need it , and it is something to do and learn during slow times.
