Greg,

Sorry to hear about that. Hopefully everything works out for the best.

NUBO,
You're an experienced hunter and there aren't too many things in the woods that sound like a grunt. You did say that some of them were really short right...well, I don't know if you've ever heard a buck trying to breed a doe but it is a similar sound to a grunt but usually shorter. It sounds more like a short clicking sound. But, more than likely if you thought it was a grunt, it probably was. He may have just had a hot doe (2nd estorus) almost in a standing heat. At that point a doe will not move a whole lot but more back and forth across a small area. I have only seen this twice but I tell you what, it sure is amazing.

Good Luck to everyone!
