Imperial Masterpiece
The railroad right of way usually has a strip on either side that is untended because it is a no man's land between the right of way and the adjacent property, often industrial or commercial. They are everywhere. Next time you cross a set of tracks, look both ways! You'll see miles of free stuff often beat up by sloppy cutting and/or half poisoned periodically. Bring a digging fork and loppers you can plunge into rocky soil.I wish it were that easy. I can not collect from most areas here as they are someone's property, the city's property, or a state park.
You're in Central Jersey, so around the Pine Barrens?
