I do not worry to much about gun fire
A perfect example , we were calling a ranch the other day working a long draw all sage brush from 8 am till about 2 pm saw 7 called 6 and killed 5 the draw was about 3 miles in length.
On your side where there are a lot of woods you have to remember the sound does not penetrate the woods like it does our sage brush country.
Calling on your side takes a lot of patience, And requires a lot of field time to learn what is going to work for you , just keep at it , Do not get frustrated and quit.
In time it will all come together for you And remember its just a lot tougher to call in coyotes on your side of the hill .

Get on google and search a coyote warning bark . That will tell you if your BUSTED or not.The hawk flying above tells me you were doing a lot right.
Barks are usually NOT a good thing BUT that coyote may have been barking at something else as well .
Tips from east side callers like me( No offence to east side guys)

Do not always apply to your side of the mountains , Its a diffrent game over on your side due to population, human and coyote , The ground, And hunting pressure .
