I wish i knew the Tuscan area for you but I have never hunted in that direction. Get a map and look for rivers or lakes, get on line and look at bird watching websites. You might find some areas that are huntable that bird watchers will post what types of ducks they see.
Your right its a lot of driving, and a lot of gas. I have hunted only a little this year. I'm job hunting and trying to save my pennies, and gas costs a lot more than a penny these days.
Have you ever woke up one day and said. Damn when does the season start.
