Looking for Catfishing tips

A friend of mine moved up here from Florida. He likes to fish for cats and asked me to take him sometime. I usually fish the lake or bay for trout, perch, or walleye depending on the time of year. I don't know much about catching cats around here. Anybody here with some knowledge on when, where, and with what, that wouldn't mind helping?

Bluegills cut up are a good bait as are shiners.
