I had to work in central today and on my way home I rode by 12 mile and there was this boat out by the road along the rip rap. He was going real slow up the bank. there was a large generator running and he had these 2 yellow poles hanging out the front of the boat with these fingers coming off them into the water. there was an old man driving the boat and a young guy standing on the front between the 2 poles with a net in his hand. I stopped to try see what they were doing but they were to far up the bank by the time I got turned around and parked.
