Given your username, I was going to mention that you need to hit up the Parklands since they stock with trout, but it looks like you may know that. That's 5 minutes from my house. .
It looks like it will be a cold week, but I'd be down to meet up this spring. I'm sure you know you can't go to state or Louisville parks (except Tom Sawyer - make sure to check in). I was going to test the Simpsonville/Shelbyville scene today, but the cold scared me away and I just scouting around town.
There is a nice poultry show every year at the Shelby county fairgrounds. That's about all that I know of the area. I am not too far but it's still a decent drive for me.
