I've been having a similar problem in my back yard for the past 3 weeks. There are a gazillion acorns lying all over my yard, nice big fat juicy ones, but yet some critter is digging holes the size of golf balls in my lawn and tearing up my grass in the process. I'm thinking it's the nutters but I can't imagine what they're digging for since there are acorns literally all over the place. I don't think I have grubs, as I put down grub treatment earlier this summer, but somebody's digging for something Fedex just dropped off one of my new trail cameras about an hour ago and I just finished programming it and testing it (it works fantastic) so I'm gonna set it up in the back yard tonight and see if I can get some pics of the culprit Jeff
