Well I don't like to but it has to be Dollis Hill

Piccadilly!

@anglophone Shit, I knew someone would think of that one.
OK Grosvenor square.

@Fernapple Hmm. Earls Court.

@anglophone Great that could be a slip. Because after two double word names in succession, I can use the double words equal double play rule, which gets me to. Hyde Park, and Hyde Park Corner.

Which is a triple, so the only way to get back to a double is with a double compound combination.

@Fernapple Watford High Street followed by Westbourne Park. Is the Slide Rule about to come into play?

@anglophone Yes, it is not very sporting at this stage, but I am not ashamed to play the slide rule. So.

Parliament Square.

@Fernapple Ouch! Battersea Power Station.

@anglophone OK I think you got me. Its hard to get more than two steps away from Mornington Crescent, even though Battersea Power Station does allow me the reverse one way street following the a wild card rule. So I will play wild card North London Line reverse Paddington Station.

@Fernapple Eek! Kings Cross St Pancras.

@Fernapple Off to a smashing start I see and opening up the Hammersmith and City this early in the game, I'll consolidate to Shepherd Bush Market

@anglophone as I appear to have cross posted with you should we active the Crossrail provission?

@MattHardy Got you, Elephant and Castle.

@Fernapple Not so fast Fernapple, you used a wild card earlier, I'm using an oyster card to take the 468 Tulse Hill. Out of the zone 2 danger area. Thameslink beckons.

@MattHardy Marylebone.

@Fernapple I feared that if I left that opening exposed it would be my undoing. No need to postpone the inevitable I suppose. Paddington via Gerrards Cross
