My pen pal and dear friend of 53 years lives in Leyton, London, have been to London (1978, 2000, 2006), and love all the sights and historic sites. I would take my life in my hands just crossing the street, what with the traffic coming at me from the "wrong" side of the street! Bicycling? I'd be a statistic within the first 10 minutes. But, more power to you, wannabehealthier!
