Before and After

It looks a bit like one of those advertising leaflets for people who come to pressure wash  your drive:  on the left - the clean drive after washing, on the right - what it looked like before washing. 

On the left is the portion that I pressure washed yesterday.  On the right is the bit still left to do, although I did another section this afternoon.  However I do find it a rather tedious task, so I only do a bit each time and the work will be spread over several days.  The clean bit does look a lot better, though.
