Geof,
I belong to the Wye and Usk Foundation but can't get over to fish too often as I live in Cambridgeshire!
I do enjoy the fishing even though it can be quite challenging at times, but that is probably due to my lack of experience on fishing for Trout on rivers as none is available where I live.
Hopefully this will change shortly as we have (hopefully) just bought a house near Llandeilo in Carmarthenshire and this should make it easier to get over.
