Glad you are okay. I had an experience today very similar. I went out in my kayake to sit on an island watching a sandbar I have been very succesful with this year (ducks and geese) the water was high but I have been fine many times before as long as I keep pointed into in the current. I misjudged the current today, it grabbed me and flipped the kayake. I ended up under water and moving fast. Somehow I came up not far from the kayake, grabbed it and held on, something hit my leg so I reached down thinking it was the paddle..it was my shotgun...ended up struggling to shore with an upside down kayake and shotgun. I have read stories about guys drowning while duck hunting but never understood how it could happen...I now know...complaceny is dangerous...didn't wear a life jacket...same as not wearing a safety harness...big mistake on my part, will not make it again.
