My scariest moment so far wasn't really too scary. I was kayaking in Georgian Bay off Manitoulin Island near Burnt Island. This is a remote area on the south west side of Manitoulin. About 6 km from camp I noticed the fog start to roll in. I turned to head back but the fog engulfed me in minutes. I followed the shoreline but had to make a 2.5 km open water crossing. I did have a small gps. But as I crossed in the fog without seeing anything for 17 minutes I realized the importance of having a compass on deck. What if my gps broke or stopped working? The fog was so thick, I could only see about 100 meters. I did buy and mount a compass after this trip. As well I realized the importance of knowing how to properly track and navigate without the use of a gps. I use and practice my navigation skills now and use the gps as a back up.
