Trump Tower has been heavily barricaded and guarded since before Trump's election win last week.
Several hundred students demonstrated, at first in a protest pen on Fifth Avenue.
Students ditched the pen en masse to march down the middle of Fifth Avenue.
Some bystanders were bemused. Others were pissed.
Demonstrators gathered in Washington Square Park after a 50-block march that was largely unmolested by the police.
