If you've never done this, then expect a lot of walking! Make sure your boots are broken in and up to the task. Also, might want to consider putting those sling studs/swivels to use. Walking 5-8 miles a day carrying a gun in your hands, on your shoulders or broken on your forearm gets old quick. Last, dont expect the birds to sit tight to the point, or until you get to the point.....I have half a dozen of these hunts in TX and KS under my belt and while some were better than others, the birds almost always jumped further out than what we expected.....lot of birds fell from 30-40 yards out. These were not outfitter hunts....just hunts on farm/crop land in "high" pheasant areas. Good luck on your trip and please post upon your return!
And if you don't walk miles every week, start doing it long before the hunt.
Lots of birds, good shooting, and you could finish up early. Lack of either, and you could be walking most of the day.
