thought exactly the same myself, don't even know why they need to extend the line as far as Portishead, a park and ride at Portbury would kill two birds with one stone be handy for Portbury and Easton in Gordano, and is less than 10 minutes from Portishead, would slash millions off the overall cost as well ,if you and me can see it beats me why the people responsible for the project can't.
