The calls will get their attention just the same as anyplace but a coyote lives by his nose. And his nose is probable the best there is. In western WA were visibility is restricted, it is tough to get everything just right. (wind,call type,terrain, ect) And the more times you try calling- the smarter they become. Every-time you call for dinner and there is none or he smells a human, you are training him to stay away. Now all these factors combined are tough to beat, but it CAN be done. I am not trying to discourage you in any way. I just want you to realize that it may take some time to figure it out.
