What a nightmare, I don't remember this being such a pain in the aris 4yrs ago.  Trying to avoid anything in and around Stanmore for the millers and the A40 Ruislip for the Shrews.  The tube all seems to go every direction but South West, obviously don't wanna go anywhere near Heathrow or central London either.

Had to plum for Raynors Lane in Harrow, as its in between
