SATURDAY IN ABERYSTWYTH You can tell it's a summer saturday in Aber by the throb of motor-cycles arriving from all directions; A lot of them are high-powered modern machines, but by far the majority are Classics from the 60's. Their deep-throated roar takes me back to the days when I was an under-graduate in Hull, where Roger , a guy on my landing, had two beautiful Velocettes, which had the incredible ability to take corners at near horizontal Quite why these motor-cyclists choose to come to Aberystwyth is beyond me; It's a dump!The beer is both dear and queer; It's full of bloody Brummies, and there is nothing to do unless you enjoy second-rate boozers.It must be the ride here that has its appeal.
