Prosperity Social Club owner Bonnie Flinner has partnered with Skidmark Garage, a collaborative workspace in midtown Cleveland, to host the tonight's special Two-Wheel Roundup that takes place at 6 p.m. at Prosperity Social Club. Skidmark Garage owner and Wrench Against the Machine host Brian Schaffran will be on hand both nights to talk shop. Local graphic artist Jon Hicks has designed the event's colorful (and collectible) flyer. Local singer-songwriter Rachel Brown will perform. Dinner and drink specials include $3 P.O.C. cans and a $10 strip steak served with handcut fries. Anyone with a bike on display will be entered in a free raffle for the chance to win gift cards, T-shirts, hats and other swag. (Niesel)
