I discovered a sure fire way to tell what direction drumming is coming from. I cover a lot of country when Turkey hunting and often I hear gobblers drumming that never gobble. Most of the time it is difficult for me to course exactly what direction the drumming is coming from. I discovered that if I get real still, hold my breath and use all my instincts to determine what direction the drumming sounds like it coming from, then turn 180° around I will be positioned just about perfect.

Sounds about right.
