Hoyt,
That's a pretty good summary except the gland is nearer the HEEL, of the deer, not the knee, the knee is much higher up in the leg. Tarsal refers to the bones the comprise the "toes and ankles." As the the OP question, I always remove them(Tarsal Glands), at the end of the skinning job as I've always heard what you were told, not 100% sure if it's true on a doe, but I had some JERKY from a buck that didn't get his removed, and it tasty like a STANK RUT BUCK SMELLS!!!! The META-Tarsal gland is actually in the FOOT, or lower ankle if you will...
