Charles,
Wind checker works great. I prefer a wind feather on the end of my bow. Ray stated that in most cases feathers don't work well due to moisture. The weekend I was there this wasn't the case as a front moved in and it was windy the whole weekend. Normally though his point would likely be a valid one, especially in the morning.
Two biggest pieces of advice. Move very slow and glass a LOT!! Personally, I tried to move twice as slow as I felt necessary and glassed every 3 to 4 steps. I saw a lot of hogs that way too. When you spot a sounder of hogs, you can move pretty quickly to close the distance but once you get within 50 yards or so I would slow it down again, wind is most important but they can see. Good news is they keep there heads down alot.
If you hunt any near the river watch the banks and don't get to close. The river undercuts the banks and they can collape on you pretty easily. Did not witness it happen but you could see several locations where the bank had given way.
Lastly, eenjoy the fire and conversations in the evenings. The fire will warm your body, there is a good chance the conversation will warm your soul.
Oh, and if Ray starts telling a story about a little pig that I personally ran into several weeks ago just cry out, "HEARD IT!"
