First week of November is usually money for me. Bucks are usually on their feet cruising all day and responding very well to calls and scents. Sometimes last week of October is hot too....but I ALWAYS schedule some vacation time for the first week of November. Of course you always get that little bit of fluctuation from year to year but it's usually a safe bet. I also would rate the first week very good if you have got them still on summer patterns and you can get the jump on one before they even realize the pressure is on them.
