I had seen a couple prior to this past weekend.This weekend I saw several,maybe 6 or 7.I have also seen a couple of half hearted ground scrapes.
I believe it is the heat.Some have suggested that when the acorn crop is light bucks don't rub as much,I had even read that in an article one time.I don't believe it for a moment though.What about area's that have no oak tree's.
