I agree with the above statements. It gets to the point where a buck may be traveling almost any time of the day. I have also noted that in the evening stands, I am more likely to see a buck as early as 1.5 hours prior to the end of day, while does are more likely seen 45 minutes to 15 minutes before the end of the day.
I hunt marshes a lot in my area, and a key is to find travel funnels. In my marshes, any tall trees are usually on ground just inches higher (and a bit dryer) than the rest and that is a key, but often, hunting the trail coming INTO one of these areas, sitting in the marsh itself, is a better bet.
