Today NH Fish and Game strongly urges that you not use bottled natural urine based deer attraction scents to prevent Chronic Wasting Disease in NH. So do your homework if you use scents New Hampshire. There are many synthetics on the market. Having said that; I have used scents all of my deer hunting life. And I still do, just avoid the urine based scents. See update below if you are planning to ship your meat or cape home. Rules apply!
