My homemade bait has lots and lots and lots of garlic in it. Turtles don't seem to like garlic. I can count on one hand all the turtles I have ever caught on my bait. All of them red ear sliders.
From Genesis: "And God promised men that good and obedient wives would be found in all corners of the earth."
Then He made the earth round...and He laughed and laughed and laughed!
