As a dog guy, I dont have a problem with road hunters, as long as they use their head and some common sense. If everybody had a dog, there'd be more pressure on the WIAs.
You never know when your ability to follow a dog is going to come to an end, with some kind of physical limitation, or a debilitating health issue. I for one appreciate that SD still allows ROW hunting. When done in the manner intended, theres nothing wrong with it and it offers an opportuntity for those with or without a dog to pursue the bird we all treasure..
I bet you'd be surprised how many ppl venture to SD with no dog.
