We have been going the 3rd week of October but are considering moving it to the last week next year. We shot mostly local birds this year as the warm weather was impacting the migrators but still had PLENTY of them around. It you plan on hunting the potholes, it can be questionable to move it any more as we have encountered ice in previous years. We generally head out on Friday at about 12 and drive straight through. That puts us in the populated areas at the best times and we avoid most of the traffic. We get out there Saturday midday and after getting settled in we get a few hours scouting. We look for an easy hunt for Sunday morning and then use the rest of the day for more scouting. We generally hunt through Saturday morning and then head back afterwards. It is a tiring schedule but well worth it. Take your camera, plenty of clothes (it can range from warm to bitter cold) and a few "local" items to pass on to the landowners as thank you gifts. I guarantee you will forge some lifelong friendships while you're out there and will look forward to visiting them in years to come. In fact, we just got done making arrangements to send Christmas hams to our favorite hosts.
My wife says I don't pay enough attention to her...or something like that. I really wasn't listening.
