"It's an all-day, and all-night event here," Kearns said. "People pack the streets downtown. It's crazy."
The Findlay Market Opening Day Parade drew thousands to downtown streets. Some streets just outside Great American Ball Park were closed for a large block party. Church bells in the city could be heard playing "Take Me Out to the Ballgame."
Logan Morrison said the festivities provided a wakeup call for some Marlins players at their hotel.
"I heard the music from the block party; actually it was pretty cool," Morrison said.
