Some longtime “doggies” of Red Dog’s Dog Days are lining up to skewer Red Dog himself during a roast Saturday night.

And everyone’s invited.

The Red Dog Roast is set for 7:30 p.m. in the main dining room at Alvamar Country Club, and that means no tank tops, gym shorts, or running shoes. Try semi-formal or even formal attire, a change of pace to help honor Don “Red Dog” Gardner and his wife, Bev.

“Red Dog is one of the treasures of Lawrence — a state and national treasure,” said Phil Bradley, a longtime participant in Dog Days workouts and scheduled roaster for Saturday night. “He gets a lot of local publicity, but doesn’t always get a lot of local respect.

“This is a chance for us, where we’re not in sweaty clothes, to tell some stories about our dear friend.”

The event is free and open to the public, although attendees may choose to show up early for a pasta buffet, scheduled to begin at 7 p.m. Cost for that is $21, and there will be a cash bar.

The roast is the brainchild of Jeff and Susie Sigler and their daughter, Melissa Sigler. All attend Dog Days workouts, now in wintertime mode: Participants show up at 6 a.m. Tuesdays and Thursdays to run, skip and jump around the concourse and up and down stairs at Allen Fieldhouse.

Summer workout sessions — either in the morning or at night — are regarded as anything but easy, especially with Red Dog behind his megaphone, directing the doggies through drills.

Like the roast itself, the workouts are free of charge and open to all. It’s a Lawrence tradition, through and through.

“We’re going to have some great stories, observations, half truths and some all-out lies,” Jeff Sigler said of the roast, which has about 10 speakers scheduled to share their thoughts at the mic.

“I’ve been around Lawrence a long time, and I can’t remember anyone ever having a roast. It’ll be a good way to poke fun at him and honor him at the same time.”
