Not certain the reasons are so obvious Trev. Certainly as you pointed out the crossbow requires less movement to shoot but other than that the crossbow and vertical bow are pretty well identical in performance with the slight nod actually going to the vertical bow. There are some good arguements to be made for including crossbows in archery season as they are in many states and provinces and there are also a few arguements for keeping them out. I can't help but think that getting hunters spending more days in the field is a good thing and certainly increasing crossbow opportunities would do that, just as increasin muzzleloader opportunities would as well.
