Anybody Know about scents and scent killer\'s??? Anybody tried scent killer or estrus scent and that type of thing? I'm going Elk hunting up towards Alaska, Ive never hunted Elk and I'm going to try Elk estrus scent and scent killer to hopefuly increase my luck. I got a video from Wildlife Research Center products which explains some what how to use scents and scent killer, I am kind of curious to hear how this stuff works? Anybody heard which brand is best or have any experience using the stuff? Thanks all! any comments welcome.
