Serendipity 2. Having parked, I approached on foot the stack of matts I'd glimpsed from the car, and then saw this one just a few yards from the stack, on the pavement but fenced off with some temporary fencing which had masked it somewhat. The fencing seemed to be there just for the mattress, but I could be wrong. A bold-patterned matt, I wish it hadn't been covered in the remains of a cheap chest of drawers.
