We hit private land. You can do this in degree from relatively high end lodges with their guides and dogs and include everything to the tune of $1k/ day to farmers who farm with an eye to keeping birds around and who grant access for, say, $175 per gun per day. At this level they may or may not have a dog(s); we had our own. We went this latter way and had tremendous shooting.

There are also public walk-in areas which of course are free. One thing for sure if you are willing to risk the vagaries of December weather is to go later in the season as things are winding down. Everything is more casual and relaxed and though the birds have been to school there are still plenty of them to be had.
