Madam, - I note that my cousin Joe Walker has not taken my advice ("Barrier erected at disputed right-of-way", The Irish Times, September 20th).
I told him that all he had to do was provide a car-park and toilets, spend a fortune on maintenance and charge a modest entrance fee. That would keep them out. It works here. - Yours, etc.,
ROBERT B. WALKER, Fernhill, Newtown Little, Sandyford, Dublin 18.
