When I was in college way back in the 1970s, I was always surprised by the number of students who went to Louisville to watch the Kentucky Derby. I never had any money for that or for spring break in Florida or any of that stuff. I felt rich if I could buy a Baskin-Robbins two-scoop strawberry ice cream cone. I remember one month I ran out of money with a lot of dirty laundry that needed to be done.
Anyway, I found this list of five free things to do in Louisville. If I ever get back down there again with a few hours to spare, I'll definitely check out their riverfront park and I'm for sure to go up on the Big Four Bridge.
