Silver City cross-channel car ferry!
Never did like boats and first took a car to continental Europe in 1959 using Silver City's Lydd-Le Touquet service. I put up with boats when SC stopped, took to Hoovercraft when I could and I've used the Tunnel since it opened in 1994 but am hacked off with their fare structure where the day-trip boozers are subsidised by those of us taking proper holidays.
