Denver woke up Friday to piles and piles of trash covering Civic Center the morning after the annual 4/20 rally downtown.
The garbage was mostly strewn around trash cans and appeared to have been pulled out of bags and boxes that had been emptied and tossed aside.

Rally organizer Miguel Lopez said volunteers were cleaning up the area around 10:30 p.m. Thursday night when a man went through the park, tearing up trash bags. When volunteers confronted him, Lopez said the man threatened them with a knife.

Organizers came back Friday to finish cleaning, he said. Their permit expires at 11:59 p.m., city parks officials said.
