After COVID took the fun out of last summer with the cancellation of regular Whoop-Up Days programming, Lethbridge’s annual fair is returning to Exhibition Park in September. Mike Warkentin, Chief Executive Officer of the Lethbridge & District Exhibition, said Friday Whoop-Up Days will be staged from Sept. 2-5 at the Exhibition grounds. Due to the financial impact COVID had on people, admission to the fair will be free, he told media.
