You certainly aren't going to get a "masters degree" in predator calling from a couple of very elementary paragraphs. There has been some very good basic advise given, the best being about the wind direction/crosswind set-ups. Keep researching and get outdoors and put solid information into play. You'll screw up some and get busted, you'll get damned aggravated at times and then you'll begin to see a little success here and there. Predator calling is one hell of a lot fun and quite challenging too. Have fun and keep learning throughout your time afield.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
