This pony track opened in 1875 and has been serving up thoroughbreds and mint juleps ever since. Get a fancy hat and some gilded binoculars in the stands or hit the infield and discover your inner degenerate gambling alcoholic. If you're not drunk enough to cry when they play "My Old Kentucky Home," you ain't drunk enough.
