The point was to mis-categorize the crossbow as a gun. That is it in a nut shell. they have widened who can use it, but have restricted how it can be used.
As for a bow being used throughout the gun season? Ohio has been doing it for years. Some guys prefer to never pick up a gun. Our season starts @oct. and runs through Jan. with no breaks. When the guns are out during deer gun, hunter's Orange is required. Works just fine!
Deer are more keyed up and alert during deer gun, But many guys still stick to the bow. It does have the advantage of silence, when every place else is noisy. That can, under the right conditions, be an asset.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
