One area I hunt in northern Lancaster County is very spotty with acorns. Most are nickel sized. But go 6 miles north in southern Lebanon county and they are abundant and large. Lebanon did not have all the rain that hit Lancaster and York counties. That's my only guess on why there is a big difference in such a short distance. It seem that north of the Pa. turnpike the acorns and beachnuts are abundant and south it's very spotty.
