Alternative route

There's been a tube strike in London. I get the bus so not directly affected, but of course the buses are more crowded. So tonight, when I stepped out of work by Trafalgar Square I went through Admiralty Arch and up the Mall, past the big house above and through Green Park to the Ritz on Piccadilly where I caught my C2 bus to KTown early on its route so it was fairly empty. Now THERE'S thinking.
