Should it be legal everywhere I will leave that alone

.
The only time baiting will significantly improve your odds at a muture buck is in areas that competition and availablity for top food sources is limited (ie: forest). While baiting will always attrack game, it often will show not much benefits to hunting a field or other dominant food source avaialable in food source enriched land. Therefore I think baiting would be best suited to be legal in areas where food is not abundant, the rest it should be hunt what is already their. In most cases that is the best solution in any regard.
BTW, baiting is legal here throughout the province in all areas, I have done it in the past but don' t anymore as it proved to be a nonfactor in the areas I chose to hunt. I have found hard nose scouting, planning and picking appropriate locations based on wind, time of year and travel routes of game to be the best technique for success.
