The pre-Christmas anti drinking and driving campaign, for around $10 the police themselves were selling a list of where all the police checkpoints were ... They didn't catch anybody!
And at the airport about the only people paying income tax were the handling agent, as the police would be coming to do a raid we'd have already had the tip-off and as a squad of police cars would be driving in to the airport we'd be at the traffic lights waiting to exit the airport to go off drinking for the day, an hour or few later the police would come and join us drinking.
As for any viable route well let's just wait and see, the UK Metropolis is London and I find myself reading suggestions of lesser catchment areas as far north as Scotland, I won't argue but let's just wait and see!
