Thanks so much for your input.
Since you are a ZOMBIE expert, please come soon for a weekend when we can arrange it. If it is ZOMBIES, I need to know. I am seeking your highly valued opinion on these scary noises in my back woods. They don't start until late. I'll throw some steaks on the grill. Then later, we can sit on the back patio and roast marshmellows as we wait for the show to start. What do you think?
