I'm a Baltimore native and I can say that including Patterson Park was an error. You don't want to be in that area after dark unless you're looking to hook up with a drug dealer or male prostitute. Besides all that most of these parks are no longer parks in the 1910's sense. They are commons or greens having long since had their horticultural diversity lost through neglect. You can get a sense of what Confederate Park was like at one time if you walk under the rose arbour when it's in bloom, beautiful and fragrant.
