Detroit - Gateway to Freedom

This sculpture by Ed Dwight depicting slaves traveling the Underground Railroad and pointing their way to freedom across the river to Canada is found along the River Walk in Detroit.
A description of their "Gateway to Freedom" is shown above. There is debate about the use of symbols in quilts in the Underground Railway. Here is one such article and there are others on the internet. http://en.wikipedia.org/wiki/Quilts_of_the_Underground_Railroad
