spot of stargazing, scottish style. so those are the stars! that is way more than you can see with the naked eye. we are off to the us now where the story of how the american civil war ended slavery in the country s southern states is well known. but what is not so well known is the story of the underground railroad. it was a secret network, which, before the civil war, help to smuggle escaped slaves out of america and onto freedom. a new tour is helping many local people from chicago reconnect with that history, and we have been to meet some of them. the underground railroad had no stations, no tranis, and no tunnels.
