Doing it on the ground has been tuff this year!! Looking out my window as I type this, the willow branches are doing figure 8's in the wind. Try to make that one work for you.
Keeping clean and using some of the scent free sprays will help at times. Bottom line is if they get a blast of "human" you probably won't ever know they were there.
Every now and then it all falls in place, and when you get the chance to kill a buck like the one posted on this thread,you will never forget it.
Be persistent,patient,it will happen.
Good Hunting,
Craig
