I am gonna go and ride my bike on the snow and ice today.... I should get the full meal deal of hard snow pack (my preferred winter riding surface), polished ice, and sections where you can't put a foot down despite it appearing to be clear, and where those studded tyres rule. I might even find some puddles where the concentration of road salt has kept things from freezing.

All this happens within a km of our house too.

Real world testing is where it's at, if I make it home without having crashed or being run over then the experiment will have been considered a success.
