You know (Gross) I use this deer calender i get from deer and deer hunter mag, and last year was the first time i gave it any thought , and the dam thing was pretty close if not right on about when deer where going to move and feed , and rut , and chase ect....... I have to look back and kind of laugh now but it was really usefull tool,, I know the drury brothers use the moon phase alot to pattern deer movement , but like your self being in the woods as much as possible at the right times is the best bet//////////////////////////////////////////////////////////////////////
