I've been replacing a portion of my wood fence that my tangerine tree had kept from falling down for many years. Well the tree died in the freeze so I'm slowly replacing the fence. I can only work on it for 3 to 4 hrs each day in this heat and humidity. I go thru 2 or 3 t-shirts, with several water breaks. When I got night leg cramps, I realized I was not replacing all the salt I was sweating out. So now I re-salt at each break. No more cramps. I'm now down to just replacing the last half of a double gate, so I can again get out my 53Willys, 56Chev 3/4T, and lowboy.
