The pod today got me thinking.  There were two times when I did a complete face plant with a canoe on my head.  Both times were in shallow water where I couldn't see the bottom. 

So I remember coming down a trail to the landing with the canoe and seeing an older solo guy who has his boat broadside with lots of small loose gear strewn about.  I had to go around him off the main part of the landing and as I stepped into the water I went down in a heap.

The tandem 17 footer was now completely covering me as I lay face down in 2 feet of water.  It took me a few seconds to crawl out from under the boat.  Well, solo guy was laughing and said he thought I disappeared when he turned around.  I was covered in mud from head to toe.  The guy was clueless and never apologized for blocking the landing.
