Sinkhole Forces Evacuations
Several families forced out when sinkhole opens under row homes.
A sinkhole has forced several families from their homes in Allentown, Pennsylvania.
Crews are working to board up the block of row homes evacuated Saturday afternoon.
About 25 people living in the eight row homes are staying with friends or family and getting help from the red cross.
Depending on the extent of the damage, the families could be displaced for days, even weeks.
There's also a chance the homes may be condemned if effective repairs can't be made.
