Check out retro exhibit in Canton

Today is your last chance to see Mom, What’s That? at the McKinley Presidential Library & Museum in Canton. On display are things that were all around just a decade or so ago, yet today’s kids have likely never seen them: an original Atari, a pay phone, an Apple IIc computer, cassette and video tapes, a roll of film. There’s also an interactive display where visitors can listen to sounds like a dial-up modem and a busy signal. 330-455-7043 or www.mckinleymuseum.org.
