We'll have to try and get there again sometime Lynne, but the problem is Blackwall Tunnel. Besides being closed southbound after 9pm Fri, Sat, Sun, they are now only letting traffic through in little convoys on weekday evenings. It took us an hour to get through the other week. Both Rotherhithe and Dartford crossings, tend to make our journey much too long. Give my regards to Richard though.
