There’s plenty on this week’s calendar, including a night of trivia, a three-day wake surfing event at Lake Lanier Olympic Park, a couple farmers markets, a day of racing at Caffeine & Octane Lanier Raceway, a dive into the facets of mystery writer Agatha Christie and a concert with The Black Gold Orchestra at Smithgall Arts Center as part of the 2024 Peach State Bank & Trust Summer Music Series.
