Everytime you use a deer stand, you "contaminate" it. Regardless of how careful you are, you'll leave a bit of scent at the stand, and leading to and from it. You'll make a tad of noise when there also. So the more you use the same stand, the more contamination you leave behind and the fewer deer that will pass by it. Use the same stand over and over again during the course of the season and you'll burn it out(as I call it). While not so much during a short gun season, during a long bow season, many times if one hunts the same spot all season, by the time rut rolls around and big bucks are vulnerable, they have learned to avoid the area. If you are 200 yards from a big buck's bedding area and have been rattling horns, and spraying scents around all season, believe me, the buck knows you're there. The only hope you might have is that while chasing a doe in estrus, he blindly walks by you. While attractant scents work, they usually only work once in a spot. Spraying them on the ground or on surrounding vegetation leaves them there and attracts deer while you are not there. Refreshing that scent on another day, in the same spot, may alert a deer more than attract it.
You already know where the buck sleeps, that is half the battle. The other half is finding more than one entrance and exit to this spot that you can get to without contaminating it, and using it only when the wind is right. Rotate spots to keep the deer from patterning you and rattle/use attractant scents sparingly and only when deer are really attracted to them. Place your attractant scents in bottles you can cover or pads/cotton balls you can remove and take with you when you leave and only avoid contaminating them with your scent when using them.
