NorthWoods primary ingredient is collected from bucks in the fall when in the rut. Refrigerator-kept until bottling is when a second ingredient, interdigital gland secretion, is added. A double whammy of natural pheromones that will outwit the territorial rut-crazy trophy buck. NorthWoods is a territorial lure which gives you the edge especially when calling or rattling. Use NorthWoods to make things happen!
