Paul and Dave,
Thanks, after seeing the pictures posted of heather I figured it was probably fescue. When I was in Ireland and NI I played RCD, Dunluce and Valley, Portstewart, Island, Ballybunion, Portsalon,Rosepenna, Lahinch, and Ballylifin. To my eye there was nothing that resembled the picture posted of heather at any of the courses I played. My guess would be it was all fescue.
