It looked like Bourbon Street in New Orleans on a Sunday morning, as the Mifflin Street Block Party in Madison wound down at about 8 p.m. Saturday.
After about 10,000 young people had partied hard for hours, the street was strewn with flattened beer cartons, flattened beer cans, broken plastic cups and — manure from the steeds of mounted police. Most party-goers had left, and a phalanx of police arrived to clear the rest from the street, leaving only some die-hard partiers on balconies and porches.
About 400 people had been arrested, mostly for alcohol-related offenses such as underage drinking and having open alcohol containers.
