Good link.
You want a tried and true tip? Try whizzing off your stand. No kidding! Back when I was on D&DH, I decided to test a whole bunch of accepted principles. One was this thing about carrying out your own urine. What got me thinking about it was one day I was out with #3 son. He was about 7, and this was his first year following me into the stand. We'd been up the tree for a couple of hours, and he needed to whizz. Rather than sending him down the ladder, I decided to just let him go off the back of the buddy stand. 5 minutes later, a doe came and walked right past the stand. A little later a small buck showed up.
That got me wondering. That was 12 years ago. I can tell you that I have experimented with this to the point that I frequently have deer show up immediately after leaking off the blind. My guess is they hear it and it sounds close enough to acorns falling that they come to investigate. I've had doe come up and smell it. I've had one young one roll in it.
In my last year at D&DH, I asked folks on the forum to try bringing a water bottle to the stand and testing plain water. A few said they'd try it, but I never got results back. The forum kind of imploded that fall, and it was turned off the next spring.
