MILWAUKEE -- Thousands of fans lined downtown Milwaukee streets on Thursday to catch a glimpse of their beloved Bucks in a parade to celebrate the city's first NBA championship in half a century.

Six police officers on horseback clopped past cheering fans at the head of a procession that included a hook-and-ladder fire truck, occasionally blaring its horn, and open-air buses and flatbed trucks carrying Bucks stars, including Finals MVP Giannis Antetokounmpo and Jrue Holiday, and the trophy they captured Tuesday night with a Game 6 victory over the Phoenix Suns.

Fans could be heard chanting, "Bucks in 6," an odd but beloved rallying cry with roots in a former Bucks player's fruitless prediction in 2013 that the team would take down the playoffs' top seed at the time.

Antetokounmpo held his son, 1-year-old Liam, atop a bus as fans along the route chanted "MVP!" Later, he shot a basketball into the crowd.

"Milwaukee, we did it, baby! We did it!" Antetokounmpo said to a cheering crowd in Deer District, the area outside the Bucks' Fiserv Forum. "This is our city, this is our city. Man, we did it! Unbelievable."

Neil and Rachana Bhatia, both 34 and from suburban Waukesha, brought 1-month-old son Zain to Deer District, saying they wanted to give Zain an early taste of being a Bucks fan.

Neil Bhatia called winning the title "surreal."

"It unifies the city and puts the city on a global stage," he said. "It's great for the city and the state. It's just bringing everybody together to celebrate something that hasn't happened in 50 years."

Said longtime Bucks fan and Milwaukee native Dameon Ellzey: "In my neighborhood, you could hear everybody on their porches screaming. Black, white, Asian. In a city like Milwaukee, that's big."

Milwaukee has long ranked among the most segregated cities in America. Team president Peter Feigin called it "the most segregated, racist place" he had ever experienced, remarks he later softened. As the Bucks drove toward a championship this year, some people were cheered by the diversity of the massive crowds that gathered in Deer District to watch the Bucks on big TV screens.

The team's ascendance has invigorated a Midwestern city far from the NBA's more cosmopolitan venues like Los Angeles, Boston or Miami -- cities that have traditionally found it easier to attract the game's top players. One reason fans have embraced Antetokounmpo is his loyalty to the team that drafted him eight years ago when he was 18.

Police estimated 100,000 people jammed Deer District for Tuesday night's Game 6. Though the coronavirus pandemic has lessened compared to a year ago, the level of cases in both Wisconsin and Milwaukee County still is rated by the state as high, with daily new cases in the county roughly tripling over the past two weeks to 80 per day.

City health officials noted Thursday that announcements of the parade had urged that unvaccinated people wear masks. Few were visible among fans on the parade route or outside the arena. The city health department said its contact tracing team would closely monitor the event.

Julie Willems Van Dijk, deputy secretary of the state Department of Health Services, predicted the two large gatherings would lead to more COVID-19 cases.

"We are concerned," she said. "We know people wanted to be jubilant and celebrate, but we know half the state is fully vaccinated and half the state is not and I assume the same is true for people in the Deer District and the arena. And I didn't see half the crowd masked."
