Ya know I got a very good education on scents and attractors on another site by Stonny Creek Scents. All those supposidly doe in heat scents you get from the Wal-Mart store don't work. You may say I used brand X last year and the buck came right to it. Well congrats but it wasen't a sex lure that brought him in it was curiosity. The substance in deer urin looses its effect in as little as 12 hours bottled. It needs to be frozen right away and shiipped that way and kept frozen until ready for use. Go to huntingchat.net and look under deer hunting and you will get a very good education on deer scents too. Mike
