This is the waterpark at West Edmonton Mall. It looks very different now, but this is what the tube ride looked like when I was a kid. I went on those rides so many times in my childhood, I can still picture every turn and waterfall in my head.
One time I got stuck and couldn’t get myself moving again and my family was swept onwards with the current and other people kept going past and none of the lifeguards were around to help me and I thought I was going to be stuck there forever. Tube rides still make me feel very anxious.
