People come here to SD all the time and try it, I don't recommend it but they do. Many hunting operations to choose from. If you're going to take all that time and effort, make sure you have a good trip.
Without a Dog and perhaps not familiar with the learning curve of getting into Wild Birds,,,,combined with a 30 hour drive, a hunting operation is a wise suggestion. It gets into the blood and you will most likely be back.... if you start out with a great experience.
The good walk in areas are often in fluctuation....depending on the crops that are being rotated around them. What is great this year may not be so the next.
