Use dog-dung. I cleaned up my yard one day and decided to use it as a cover scent. I kept the bag outside by the garbage cans for a couple days until I threw it in the bed of my truck (bagged up and in a box) and went hunting. I threw it out in the field behind the barn I sit up by, took a seat by the barnand waited. I can see fields everywhere I look and lots of ground to watch them come in. After about 15 mins. and no calls, I saw one coming in. About 6-7 mins went by before I took the shot and dropped HIM at 196 yds. He was headed right up to my German Shepards poop. I use it as much as I can stand to have it laying around my yard,outside my house, or in the field. If the wind is right I will use it and will swear by it.I hunt from the same spot everytime soI only use it if I have it and if the wind is right. The wind is key.....trust me.
