Which means that, sooner or later, you’re going to end up paying for the injuries suffered by a cyclist who looses control and takes a serious spill because of it — assuming you’re not the one it happens to.

And if two months worth of sand piled on the bike path isn’t a known hazard, I don’t know what is.
