Activities at this weekend's Monster March included a costume contest, a charity walk to help prevent suicide, live music, face painting, "Thriller" dance lessons, and a mechanical bull. Yes, a mechanical bull. Check out the frightful festivities at City Hall Plaza.

Pictured: Paloma (dressed as a ballerina), Markeljana (dressed as a bride of darkness), and Genesis (dressed as a monkey) listened to live music. "We thought a lot of people would dress up," said Markeljana.
