Where could you possibly go that doesn't have catfish? Every area of the country I have ever been has catfish.
All the man made lakes southwest of my house in central Wy- & southwestto the colorado state line & the platte river system thats supplys them that we normaly fish has no cats( dosnt even have bullheads
