Slippery when wet

First snow! Although by the time I got out to see it it was indistinguishable from slush. Oh well, I decided to ride to work anyway, mentally prepared for slippery roads. But that was unnecessary, I got to work just fine… at least to the garage. 5m before the bicycle rack there was a trickle of water, I was turning while riding over it and there we go. They weren’t kidding when they put that Slippery when wet warning sign on the ramp. It was like ice, and I should know, I’ve done the same mistake on ice as well.
