This is the last update I could find. Not to sound pessimistic but I'm wondering if they went off the road someplace and they just haven't been spotted yet? There are few different ways to get from Philly to South Jersey from what I remember, having lived in Philadelphia before. I wonder if anyone has scoured the possible routes? It's a huge task to cover the highways, woods, sidestreets inch by inch.
P.S. How do I attach the link with my own title?
