I saw dozens of blue herons, four alligators and many alligator gar. One gar violently jumped out of the water and knocked into my kayak and gave me a heart attack. Along the way, I saw several people in boats and on the various sandbars, and in the water.
There were lots of stretches that I was totally alone and saw no one. This was my very first "trip" and for me it was too long and I was a little wary of the gators. Also, the current was pretty much non existent, and at times there were prolonged periods of paddling into a strong wind with the wind nearly blowing my hat off my head. This made for a longer trip. No big deal though, if you go early enough in the day and with a buddy. I wouldn't do it again alone, and I would seriously monitor the current before doing it again.
