Saturday, Aug. 12, was a big day for a lot of walleye anglers as they attended the Chase Parsons Fishing Seminar at the Okoboji Blue Water Festival. Parsons, who has been a highly successful professional walleye angler for the past 20 years and owner of the Next Bite TV program airing on the Discovery Channel, right away told a packed crowd, “I want to talk about techniques that we can use from one body of water to another.”
