We’re willing to bet you’ve never tried fishing like this! First of all, you need to make sure you’re fishing out of a storm sewer. We shouldn’t have to tell you that you don’t want to try this in a sanitary sewer. Then all you have to do is bait a hook with a bit of hot dog since catfish love them so much. Once you’ve got it dropped through one of the man hole slits you can rest a 3 ounce weight on the line. Once you look and see the weight stuck in the slit you know you’ve got something on the line!
