need to know what a vine weed with red berries that look like rasberries is....
What you describe could be wineberries, but we would not encourage you to eat anything without a definite identification.
Wineberries are a non-native invasive plant and the reddish, heavily thorned branches is one of the characteristics of this plant.
Native wild brambles like blackberries are also common in Maryland.
Here is a publication from Penn State University on wineberries: http://extension.psu.edu/cumberland/news/2011/wineberries
