Thanks for the info all.

With the tall wheat fields and the wooded patches between fields I don't have to worry about them being in the open. I'll be luck to get a 50 yard shot with the woods and the wheat (I think its wheat) is up to my chest so I won’t get a shot there. The little boom box I was using didn't have the volume to get through the woods very far (I think) to call any in. I'm going to building an e-caller, well, build an amp to hook up to a loud speaker and attach my mp3 player to it. With a Johnny Stewart CD maybe I'll have better luck.

Johnch - I'll start with the volume low and work up. I never really thought about it and just started with it cranked.

Swampbird - Thanks for the idea on pup distress, I guess food is o-plenty in the spring. I would love to work up to a mouth call but I really want to see if I enjoy hunting coyotes first. Everything I read says it can be a challenge and addicting. If I like it and plan to continue I'll try working on the Art of mouth calling.

Thanks again.
