My car is going in to the dealers on Friday for a fuel pump change (subject of a recall).
I have been told to have very little fuel in the tank when I take it in. In the past month I have only driven about 50 miles and there is enough fuel for another 200 miles.
So consult the OS map - a nice scenic run from Llandudno Junction down the Conwy Valley to Betws-y-Coed, eastwards along the A5 to Pentrefoelas then northwards (A543) towards Denbigh and Denbighshire. However, just before crossing the border turn left up an unclassified road, passing Llyn Aled and on to Llansannan, down to Abergele and home. That should take up about 60 to 70 miles.
Still need to use up another 80 miles or so ... from home to Abergele along the A55 is 10 miles (20 round trip) and from home to Llanfairfechan is about the same.
That should do, and I won't be crossing the border!
It's the opposite of being in the Dukes of Hazzard, fleeing the Police and crossing the county line!
