How about: "Jim - I can see you across the valley, the 12 point is bedded to your downhill to your left left, about 50 yards out - get ready - I'll whistle and see if I can get it to stand up.................bang"

I'm sure the intent of the law is to avoid stuff like this - I'm not sure how easy it would be to enforce - do they have to tape the conversation? How do they verify who is talking?

Anyhow - I doubt there is much enforcement going on - or even needed.
