Good gracious Bob (ketchdana) I'm astonished that the Magic Roundabout is still there! You're quite right, it was totally confusing and almost impossible to negotiate safely. The sign just before one approached it looked like a piece of knitting, or a bowl of spaghetti. I wonder just how many bad accidents have occurred on it? As I had a prisoner to visit at The Mount prison for a period of several months, I took to parking outside the town and taking a taxi to the jail instead. The taxi drivers laughed their heads off about it; they seemed inordinately proud of their Magic Roundabout! I used initially to arrive on the visit chalk white and trembly; the officers thought I was nervous, and always searched me extra carefully for smuggled drugs!
(Sorry about the thread drift, but Bob's answer has interested me so much.)
