A Father (41) and Son (21) were reported overdue at home. A search was organised with the help of Keswick MRT and SARDA Lakes. They were eventually located by LAMRT on Gunson Knott. They were cold and benighted. Team members stocked them up with hot drinks and food and they were escorted off the hill at first light. Last heard on the phone to home promising to never go walking in the winter again!
