Hot as hell. Sweaty... You hit the nail on the head.
Yeah, it was hot a blazes but the river was was crystal clear; You could see the grass and Alligator Gar at the bottom. Clear until you reached a place called Bloody Creek where the tannin in the water turned the river dark.
I’ll always remember coming around a bend and seeing about 20 gators lined up on the bank sunning themselves. As we approached, the first one took off into the water, then the next, and the next, all in echelon until the bank was cleared. Reminded me of crocs in a 50’s Bwana safari movie.
