Borrowed my dads pickup one deer season and had some tinks #69 spill on the front seat. 6 months later while towing the boat on a fishing trip my dad commented that his truck smelled funny since I had borrowed it last fall.

I have no experiance with it on blacktail but used it very succesfully back east on whitetails. I would pour some on a rag and drag it behind me on my way to my stand and then take soaked cotton balls and sprend them around I had one buck come running up the trail I walked in on and sniff the rag and cotton ball around my tree stand.
