Put in at this park 33.572821,-83.902084 and head up the yellow river. There’s a power tower ruin by the park you can explore on foot. Paddle up river for a bit and then ditch the boat and sneak up on the ruin from behind to remain out of sight (as if anybody cares). Back on the river, if you can make it under the I-20 bridge, there’s a cool old railroad bridge that tower’s above the tree line.
