The Knoxville Chamber of Commerce is hosting their annual fall auction Saturday evening. This year, the theme for the auction will be “A Spooktacular Bash for Cash.” The event takes place at Dyer-Hudson Hall. Social hour starts at 5pm, with dinner at 6. Chamber Director Aanna Hoch says that people are invited to dress up in costume if they wish. Auction prizes include things such as Iowa Hawkeye memorabilia, gift certificates for oil changes, and Iowa State men’s basketball tickets. Auction tickets can be purchased at the door Saturday. They cost $12, or $20 for two.
