A lot of folks spend a ton of money on boats, rods, and other gear. That's city-fide. The way we do it around here is too simple.
You'll need; a row boat, pond, chewing tobacco and a base ball bat.
Row out to the middle of the pond and spread the tobacco out all around your boat. Give it time to sink to the bottom. Then wait a few minutes.
When the catfish come to the top to spit the tobacco juice out of their mouth - hit them over the head with the bat and put 'em in the boat.
