I think you may have heard this before but, What are you afraid of, actually calling one in? Be subtle and passive, it doesn't work every time but it can't hurt in a no shot anyway possibility. I'm still not a fan of blind calling though. I call when I see one.

This morning I turned a spike totally around to come right in. I've called them from 100's of yards to a shot and just this morning I called in 2 coyotes and almost got a shot on them using a doe contact call.

As long as your not too aggressive, you might just be shocked.

And for the record, had my arrow connected I have a feeling one of the two on your wall would not be yours because of the call.
