I don't think the line banning beverages of any kind is necessary. Lots of folks carry water around when they're walking. That line just sets them up for a violation if they happen to step onto the grass around Lee. 

And the prohibition of signs being attached to the monument would go directly against the idea of adding signs for context, wouldn't it?

But really, history alone is not a reason to continue to have a statue to someone who fought against the United States in the name of "states' rights" in order to uphold the idea of owning other people. How does this reflect our values as a city?
