RAF Valley has the A55 near by, the west coast main line nearby so there are good links to it Grey.
Said today that 200 people (OK not a lot!:D) do travel everyday between the north and south, and that a number of buissnes men do use 6G from LPL to CWL. So the need for it is there. You try traveling in a 2 car train on a 5 hr journey from Llandudno Junction to Cardiff 😀
