St outlet John’s river cattle

I came across these grazing cows, calves and Cattle Egrets kayaking on the east channel of the St Johns river west of Cocoa, Fl. I was raised on an Iowa farm and am used to feeding cattle on pastures & in feedlots on clover, alfalfa, ground corn, silage etc. so it was a surprise when I first time I kayaked the St Johns and paddled past them. I always look forward to seeing some now when I go there. The habitat conditions on the river changes yearly with the seasonal rainfall. I found the driftwood after a hurricane several years ago and have been hanging on to outlet it. The wood was ripped and fabricated into the frame. The wood was sanded, glazed with several colors, and all surfaces were sprayed with satin acrylic finish. The photo is an 11 x 14 inch. The outer dimensions of the frame are 13 1/2 by 17 inches. It is 1 3/4 inches wide and 3/4 inches thick. The rabbet groove is 1/2 inch wide by 1/2 inch deep. Rabbet dimensions are 11 3/8 by 14 5/8 inches.
