RE: deer scents
One product that I used for the past couple of seasons now is called BowHunter's Setup , it comes in a spray bottle you spray it onthe sides of your boots not the bottom and as you walk along a well used trail your boots brush up along the tall grass it leaves a sent trail to your location.
You can also spray some on leaves and twigs as you get closer to your stand , the deer seem to love this stuff as they follow this trail , they will stop to sniff and chew on the leaves and twigs that you have sprayed.
Sent drags work better if you start from your location and walk away from your stand as every hunter knows the sent will be stronger at the starting point and once the deer picked upthat sent they will follow it to it's original orgin.
Using a double drag rag is better allowing the hunter to lay two diffrent sents such as Trails End from WildLife Reshearch and Tinks No #1Doe Pee.
