Having lived in the UK for awhile now, I've become pretty accustomed to scenes of mass public drunkenness. But nothing compares to the insanity of Saturday night's tube drinking party, when an estimated 50,000 people descended on London's circle line underground stations and trains to hold a booze fest the night before the new London mayor's public transport drinking ban was to go into effect.The chaos and destruction that followed shouldn't have been surprising to anyone familiar with British drinking culture. But the complete ineptitude with which the new mayor handled the drinking ban roll-out may be just a preview of the new London.
