I dont post often, obviously, but I hunt predators quite a lot during the fall/winter, and just want to say that most guys that hunt coyotes even semi seriously have a ton of respect for them, and are not the bloodthirsty killers they are portrayed to be in a lot of non hunting"objective" articles you read, no more than any other responsible hunter.
As a matter of fact, most seasoned predator callers honor a self imposed moritorium on hunting during the spring/summer months.
Gonna drop a couple sites you can check out,will delete if not allowed:
NPHA (new forum)
Predator Masters( already mentioned)
Predator Professionals
Predator Wild
California Predator Club (already mentioned)
and a ton of others are out there.
(Check out all the custom calls!!)
