The Under Ground Railroad was in Northern Minnesota.
It was, but it wasn't literally a railroad.
No, they just needed it to be night time and to get to Kentucky and go to the under ground railroad.
It was secret like being under ground.
Rosa parks made and took the under ground railroad
umm... i think it came from under the ground
the underground rail road was not a place but a network of people who helped slaves escape to the north and Canada
she went under the under ground railroad
No, its called the underground railroad because they were "hidden".
