Just a quick question about a spill that has appeared along a large section of my route home from work...

It looks real black when i'm heading the direction it was spilled and almost invisible when i'm coming the other way.

Anyone have any idea what it could be?

Haven't come to grief on it yet. It may, in fact, be something that isn't slippy. But it's hard work trying to stay off it round the bends. It zig zags up the middle of the lane for a k or two.

P.S. I'm colourblind so no idea if it is actually black... but it's dark! (from one direction)
