This week we look back at 40 years on the local airwaves with Mark Kiesling, who just retired as senior news anchor at the local ABC affiliate, WSIL-TV. On this, the 20th episode of “Squared Up,” we discuss the public’s reaction to the surprising news, ask Mark to recall some stories from his long career, and hear his secret to remaining at peace despite circumstances. We also share some new images from Tower Square and a photo from a Halloween party that Bill and Monica attended.
