I have shot more out of the blind than in one. The most important by far is they must not see you period. I use terrain to the max, washouts, deep cowtrails, edge of canyon lip etc. All I know is when they see you, you better be ready to shoot. The other day I called some up, I wass in full camo including face, hands leaning up against some trees, 3 toms and one hen came up to ten yards, when I thought they were settled down I tried to draw fast on them, My bow hand only made it up to about 4", It looked like a turkey gernade went off, They blew out of ther like they had rockets tied to there rear ends. Another thing that helps is being able to hunt where there is a high population and low hunting pressure.
