I always like looking at these tiny ferns which grow in a wall at Port Carlisle ... think it might be Maidenhair Spleenwort.  More fun and games at home.  This time the central heating boiler has packed up, or maybe its the thermostat as its making weird noises.  Good job I've got a woodburner to keep me and Misty warm!  Somebody coming to look at it on Monday morning.
