Stopped by the cops!

Just heard from Trish and Graham. they have about an hour to go before arriving at Mergouza where they are setting up camp for the night. Earlier Graham was stopped by the Police... and congratulated(!) for driving at the correct speed through a small town!! Apparently theirs was the only car to do so. Sounds like the Police there favour the 'reward good behaviour' tactic rather than punishing the bad! Trish said 'Guess who was nagging him?!'
