Is there something happening that I'm not aware of? I've heard that when acorns drop early it means we're going to have a hard winter. Oh boy, are we ever in for it if that's the case! I was just outside dumping scraps into my compost pile. I realized that all around me I could hear subtle dropping, hundreds of them, on the leaves and ground all around me. It was amazing. I thought perhaps it was a squirrel or two having fun way up there in the high limbs but, no, that wasn't the case. It was happening all around me from several trees. My backyard is littered with acorns and acorn pieces. It's interesting and perplexing all at once!
