I noticed difference in rut activity over the years and chalk a lot of it up to the calendar. I don't know how to explain it, but here goes. During archery, many times doe go into heat right on Halloween. I started to notice that this varied from year to year and I kind of thought it was because our numerical calendar does not follow the natural world calendar. Halloween is not on the same day every year. Did that make sense? It would be the same with the rifle season. Even if it is on the same numerical day every year, it is not really the same day. On the moon phase thing. I recently read in the PA Game News that the biologists say it is horse#$%&. I could not agree more.
