First off I live in maryland and was thinking of getting one of these and had a few questions. First it comes with a 4 oz bottle how long will this last before I need to buy more scent.Second how many marylanders have used it and had sucess. Third when should I put it out i dont want to put it out to early and scare deer away.I think I am going to put it near my feeder and set my camera upby it and let me just say to all the othermarylanders out there this wind sucks.Thanks any info is appreciated
