Greg Dafoe, of Sioux Falls, checks out a 1967 Corvette while walking through the Winterfest of Wheels indoor car show with his wife Janelle Dafoe on Saturday, Feb. 14, 2015, at the Sioux Falls Convention Center in Sioux Falls, S.D. Dafoe said he and his wife go to the car show every year. "I grew up with these types of cars," Dafoe said. "Not only do we get to look at cool cars," Dafoe explained, "it's a good cause." Profits from the Winterfest of Wheels indoor car show go to Cure Kids Cancer. The show will also be open from 10 a.m. to 4 p.m. on Sunday.
