c903,
Your idea about the cord....while tongue in cheek really isn' t too far fetched if it was possible due to all the trees and such getting in the way, but if you could magically extend that chalk circle to say 100 yards and your " Double Lung" deer isn' t inside that circle, from my experience you aren' t dealing with a " deer that will be back another day" (and I know that was tongue in cheek as well), you are (from my experience again) simply forced to accept the fact that something other than your " perfect" double lung shot has occurred and you' d better start assessing what to do next.
