The Saskatoon Ex loomed large in the summer of 2012. We lived in a little yellow rental house a few blocks from Prairieland Park at the time — close enough to watch the nightly fireworks from our front porch. I was working at the racetrack that summer, so I had a free all-access pass to the grounds. I normally stick to the swings and the roller coasters, but that year, emboldened by the all-access pass, I tried everything including the Zipper — and while I will always be up for the giant slingshot, the Zipper isn’t one I’m eager to repeat.
