I use Buck Fever forehead bf gland synthetic on the vines. I like synthetic lures over supposedly real stuff. Ive had redfox track me to my stand wearing synthetic redfox urine...that sold me. Ive also had a 6 pt buck stand down wind of me 40 yards sniffing the air but didnt smell me and that was using the same cover scent. I spray the vines with lure and pee in the scrape. h.h.
