OK, I admit I was at fault but myself and loads of other vehicles have subsidised the Welsh economy at the weekend, so they can carry on ejoying free presciptions 
Vehicles were parked on both sides of the road just down the road the Pen Y Pass turning. There is are some areas prepared for parking and then other areas are just verges
Beware - this is actually a clear way, so if you decide to risk it then make sure ALL four wheels are OFF the tarmac. There is a white line, but I did not see any Clearway road signs in the area, in fairness I didnt look, I copied what others were doing. (Except Milly who sensibly parked on the other side, as far off the road as possible.
I can only assume this regular money spinning excercise will continue, as long as muppets like me dont look for ourselves.
