BALTIMORE -- Maryland's U.S. senators Sens. Benjamin L. Cardin and Barbara A. Mikulski joined New York Sens. Charles Schumer and Hillary Rodham Clinton Tuesday in introducing legislation that would establish two parks honoring abolitionist Harriet Tubman.

One park would be located on tracts in Dorchester, Caroline and Talbot counties on the Eastern Shore of Maryland. The other would be in Auburn, where Tubman lived after escaping slavery.

Tubman was born in Dorchester County, Maryland, where she spent nearly 30 years as a slave before escaping in 1849. She later returned and led hundreds of slaves to freedom for more than 10 years as part of the anti-slavery resistance network known as the Underground Railroad.
