Me and another fool went on a rock run around Tallahatta Springs. We got in a creek and felt around on the bottom, then dug through coarse sand to pull up chunks of rock. We were in 3-4 feet of water. Stayed in from 10 till about 4 with breaks to lug buckets up the bank to the truck. We got about 1/2 ton of rock. All was well until the next day. Woke up with my hands tingeling. I had gotten them soft and ground all the tough skin off. My hands are still as soft as a baby's a week later. Bill
