The PAGC has tried to do something good but they won't provide the deer with enough nutritious food sources to aid those "immature" 2 1/2 year old deer with what is needed to grow impressive racks. This is why Pa is ranked no. 1 in the nation for deer/vehicle collisions. The deer aren't provided with enough palatable nutrition in the woods so they eat along the road.
The vast majority of our bucks are not harvested from lands controlled by the PGC and the vast majority of the roadkills do not occur in the heavily forested areas of the state. WMU 2G has the lowest buck harvest rate in the state even though it is one of the largest WMU's and is 90% forested. The deer in most of the state have nutrition that is more than adequate to produce large racks. The major factor that limits the development of trophy buck is 950,000 hunters that prevent the vast majority of bucks from reaching 4.5 years.
