This also reminds me to let everyone know, if you all don't know already, that the National Park Service is now completing the Harriet Tubman Resource Study. When they are finished with the Study process, they will recommend to Congress (next fall) the most suitable site to dedicate as a National Park or National Memorial to Harriet Tubman. At some point they will be asking for public review and comment before it heads to Capitol Hill.
You can follow the progress of the Study at www.harriettubmanstudy.org and offer your opinions/knowledge.

Best, Kate
