LOUISVILLE, Ky. (WDRB) -- Waterfront Park will be transformed into a lively scene Tuesday for Senator Bernie Sanders and his supporters.  

The public can start entering at 4 p.m.

And while a big crowd is expected, a bike rental place at the base of the Big Four Bridge won't be giving out rides. 

Wheel Fun Rentals will be closed on Tuesday as a safety precaution for the large looming crowd. 

"I don't think there has been anything like that down here," said Collin Gallus with the rental shop.

Across town at headquarters on Bardstown Road, volunteers for Hillary Clinton's campaign spent Monday afternoon indoors making calls. 

The catch? They weren't pushing Hillary, instead chatting about her better half. 

"Bill Clinton is going to be here in Louisville," one volunteer said on the phone. "Is that something you would like to know about?" 

Bill Clinton will be at the Kentucky Center for African American Heritage in Louisville on Tuesday.

The event starts at 3:15 p.m., and supporters know this is a key visit as the Kentucky primary nears on the May 17.

"They are taking Kentucky seriously," said Tina Ward-Pugh, a Clinton volunteer. "They want to win Kentucky." 

The last time Kentucky was a blue state, you have to go back to the 1992 and 1996 elections when, you guessed it, Kentucky voted for Bill Clinton.

Supporters hope Bill's visit will pay off for Hillary in the long run. 

"It's our goal, the campaigns and our communities across the commonwealth, to turn Kentucky blue again," Ward-Pugh said.
