I gave up after 3 days of pouring kettles of boiling water on to it as there was no difference. I remembered that on other occasions after a shower of rain or two they always disappeared. Low and behold, after yesterdays heavy shower of rain the mark is almost gone. What is in our environment at all?

seen before until today. Crossing into Switzerland I found road works and temporary traffic lights with a visible clock timer on them! I arrived that it was going down from 29, so I don't know at what time it started. Perhaps 60 seconds. I know that the Swiss are maniacal with their clocks and punctuality, but this is something I would never have imagined to exist. Or perhaps it exists also in GB?
