Frisbeeing a culture token to IJB for preknerdled advice, gratefully acknowledged, I emulate the Hopkins Progression and digress to Covent Garden. For the mimes, natch. Ooh b*gger! 'Oo stole me walle'?
Ah! The Hopkins' Flange (note the apostrophe - she came up with it not only after the Progression but also her unfortunate but amazing accident) takes me to... let's see, my chart says Euston Square.
Ah ha! Invoking the Sixty-Fifth Perorgative I can thus use the Green/Green Lateral loop moving to Wood Green and jumping with the double twang bonus to Cockfosters.
