I would think PA will try to implement Sunday hunting in a similar way that MD did. Sunday hunting only on certain days (1 Sunday in Novemeber for bows only and the first Sunday of firearms season) and only on private land and only with permission. The problem MD had with opening Sundays on public land was that the horse riders and bird watchers and hikers complained it was unfair that they didn't have a day to be in the woods on public land during hunting seasons. So, to quiet that crowd down, they only opened Sunday hunting to private land.
