Never done it. I hunt Walk-in areas and don't think road hunting would gain me much respect from the landowners. when I see birds congregating in the ditch I usually get out of the truck and flush them hopefully into a field I can hunt. Then I park and put some dogs out and go after them. they are apt to move in the time it takes me to get where I saw them light but for me I like to watch the dogs work. Where do you hunt that it is legal to hunt the road ditches?
