Two of the highlights of visits to service areas during my younger days were the views from Aust of the Severn Bridge, and from the viewing platform at Forton.
Unfortunately, despite Aust now being called (inappropriately) Severn View, the current building has views only of the car park and filling station; while the tower at Forton was closed on the only occasion I've been there in recent times, which looked as if it was a permanent closure.
Maybe patrons don't want views these days, as they're too busy catching up with Facebook, Instagram, Twitter or whatever.
I've never got to go up the tower in Forton unfortunately.
It does remind one that real care and planning went into their design back in the day.
