Right about now until the 20th of Nov I'll be using estrous scents. I recommend using either Tink's or Code Blue. Both will run you around $8-$10. Buy some wicks (white "P" looking things) and put some on them. I usually put out 2-4 around the area I'm hunting in every direction approx 5-10 yds from my stand.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
