I'd rather drift or jig for walleye if the conditions allow it, but trolling is a good way to cover a lot of water and put fish in the boat. I was out yesterday, picked up quite a few walleye right off the bat trolling, got an idea of where they were, then went back and drifted with night crawlers. Spent more time putting worms on my hook than fishing, couldn't keep a worm in the water for more than a minute without a white perch, drum, or catfish pecking away at it. Kept that up for about an hour then went back to trolling and catching walleye.
