While I was at the Gateway Arch I got this stamp for the National Underground Railroad Network to Freedom.
The Old Courthouse is important for the National Unground Railroad Network to Freedom. At this courthouse there was a lot of legal challenges for the slaves. The masters use to auction the slaves of on the front stairs of the courthouse. There was the Dred Scott and his wife Harriet trial who were sued and granted their freedom.
