Hey buzzard bait, those glands that everyone collects on the legs...the ones that often come with the hide when you skin, well near as I can tell they are regional lymph nodes. Why do you use them in lures? :?
Now, don't go gettin excited no one said you couldn't use them in lures or that you shouldn't use them I just wondered why use them ...they don't have anything to do with scent marking etc.
Now the gall bladder release a concocktion called bile salts thes enzymes help in the digestion of lipids I could see where this additive would make things happen. :wink:
