I found a bottle of Special Golden Estrous in my refrigerator from last year, and it says "Use in 2006" on the back. How long will a bottle of this stuff last/work? Also, what are some good scents youve used to get bucks in? There is a monster running around within the mile and something tells me that bait isnt gonna be the trick to get him in. So what is a good method to get him in my woods? Thanks for the help.
