Friend tried a new trick.
He simply put a stick in the ground about where he wantd a Deer to be in the small field by his tree stand.
He also put in a trail cam and, as he suspected ,every animal passing by at night just HAD to pee on the stick a it stood bout 18 inches tall and 2 inches around in the low grass.
After the stick was saturated for a night or two every Deer that walked into the field just HAD to go and sniff the stick.
Arrowed his a bit before dark on his first sit.
Novel idea that I had never heard of before- no scents no attractants added- just nature doing what nature does.
