National Hamburger Day

Today is National Hamburger Day.

Yep, that's a thing. 

But did you know that the cheeseburger was invented right here in Louisville?

The story goes that, in 1934, Margaret and Carl Kaelin were the proprietors of Kaelin's Restaurant in the Deer Park neighborhood of Louisville. Carl got the idea to add a piece of cheese to his hamburger, and the rest was delicious history.

Kaelin's closed a few years ago, but it holds a place in Kentucky lore as the home of the cheeseburger. 

Happy Hamburger Day, y'all! Who serves your favorite Kentucky Hamburger?
