oooh lucky you, shaney, I didn't get to see the tall ships as they were way down at Woolwich somewhere and I couldn't find any information about exactly where. Apparently they'll be back in a year as part of some global race, so maybe I can try again then.
This weekend is the Great River Race

an excellent place to see Viking longboats crewed by Smurfs etc, but it might rain and old sea salts like myself don't like rain.
