Silver Springs crew

I'm going to miss them this summer.  My last chance to kayak with the group and we had a perfect day.  The Ocklawaha was high and flowing fast.  We were on a mission to find a historic settlement called Grahamsville.  The people who lived there produced turpentine.  There is suppose to be a cemetery but alas, didn't find it this trip.  We have found the best location for it but looks like it has dissolved into history, as things do in verdant Florida.  
My friends are patiently waiting for me to return from exploring and photographing a promising location.  It looks like they are sitting in grass but its the seeds of water lettuce, an invasive plant.
