Deer glands/scents

[lakevet]

Has anyone taken the glands (tarsal, interdigital, etc.) from deer you have harvested and used them later for scent? Can you freeze them or is there any other way to preserve the scent? I have heard of it being done but don't know the specifics. Does anyone know how the commercial companies prevent the urine from decomposing and becoming ineffective? With the possibility of shooting multiple deer, I would think using deer recently harvested would be the most natural and freshest possible. Perhaps there are some trappers out there that could help. Don't forget to take a kid or two hunting!

Thanks
