One problem with a drag rag is that it could work in reverse if you use one too far and don' t freshen it as you go in. Like anything else when it comes to trailing, animals trail in the direction from the weakest to the strongest scent to determine direction. If you apply scent to far from your stand and walk in a deer will actually trail your drag in reverse because the strongest scent is going to be where you started, not quit....applying more often might help prevent this however there are no gaurantees...
