Over several weekends replaced four waymark posts on the headland path parallel with the new A5 road. This is on the Chalgrave/Houghton Regis parish boundary, HRE15/HRE13, HRE41/CHA15, HRE41/CHA18 and HRE15/CHA44 . The route is part of the revised Icknield Way path. While we were there we also collected much litter, which possibly blows across the field from the A5. Also cut back any encroaching vegetation on the path.
