This is something that ive experimented with but really havent had any luck with as far as pulling a big buck in. I did have a doe come in and check out a doe urine that we were using that was air freighted from a place in pa. fresh and refrigerated. I think the main thing about those scents is using the right scent for the right time. But to know the right time youve got to do a lil work in the woods and also you have to know how to read sign. Also I think the scent that you purchase should be up to dateand should never be applied to your clothing, boots, etc. Always use a sterile guaze or pad and wear rubber gloves. Im hunting a totally new area after hunting on a piece for 4 yrs. But since scouting a lil here and there ive keyed in on their travel routes, beeding, etc. trying to figure the herd out. Ive been hunting for along time and just last yr had a grunt tube accually work for the first time, so its just a matter of time until I get the scents to work. My main goal is to stay as scent free as possible. Thats what I love about Deer hunting its always a learning experience. Id say experiment and have fun.
