Well the message must have got through at KCC and in double quick time - only three days after Roger's communication (post #7).
As I made my way up the A20 towards Folkestone at lunchtime today there were several "gangs" of workers clearing rubbish from the verges and leaving a multitude of stuffed orange sacks for subsequent collection.
It will be interesting to see how long it takes to revert over the coming days and weeks though.
