My Watermark is Lake Ontario.
My most favourable moment was on Lake Ontario when I was attending Queen’s University for Engineering. One winter, the ice froze over very, very smoothly, which only happens rarely. On these rare occasions we used to take the bedsheets from our residents and have the wind blow us across the lake, with the bed sheets. It was an amazing experience!
One of my fellow classmates even made a nice sailing boat, and was going 40/50 miles/hour. It was amazing.
