Mid- December should not be bad, but there are so many factors - I have hunted with many guides and they scout each day, yet when you go to the field the next morning, the weather might not be right, clear bluebird and the birds won't come in. The birds decided to sit down in the field next door. One time the guide said, the birds picked up and went the other direction from their roost. One time - the wind direction changed, birds not using this route. Sometimes it comes together and you have a good shoot. Not as many birds come to Texas, but it is still fun to get out.
