I have found myself more moved by the Cutty Sark blaze than I expected. It is one of the best known landmarks in SE London and I have visited it on many occasions.
If you want to help rebuild the Cutty Sark, either by donating time or money you can do so here. I would strongly advocate to give whatever you can, you even get your name in lights (well on a list).
While Bexley and Bromley eyes are turned to Greenwich it is worth thanking Bob Neill MP for bringing the Blackwall Tunnell situation to the attention of the House of Commons. He raised the issue in an adjournment debate on the 17th of May, you can read the hansard report here.
