I remember my dad on 2 different occasions coming back to camp and reporting a "growl". This happened long before thecall started getting famous too.The first he had not seen a deer when he heard the noise and wasn't sure what had produced the sound. A few years a later a mature buck stood in front of him over a doe in heat producing the same sound he heard years before.

He jumped out of his chair after reading the article on it after I told him he was crazy both times.
