you missed beatersville by a few weekends. i dont think there is really much going on here... ever. let me know what kind of bars you are into and i can steer you in the right direction.
Like The Shark said, the cruises in Louisville aren't much. The NHRA Hot Rod Reunion is that weekend in Bowling Green, KY about 115 miles south of Louisville. Thats where I'm going.
Check Fridays paper I believe its the feature or scene section there will be a list of cruises going on this weekend. Friday there is a cruise at Ralleys on Dixie Highway and I think there is a cruise on Preston in Hillview Saturday night
