I go until it snows, temps be damned..
Once the snow starts to fall the salt trucks do their thing and the roads are covered in it, ruins bikes, and add to that frozen ruts that car tires leave all over *( anyone here ride motocross on badly rutted tracks?.. it's like that but without the power to keep you upright )
Temp wise, -10 celcius + windchill factor is harsh but i've done that a fews times ( that's 14f for you americans ) at this point, i drop the winter riding gear and switch to snowmobile gear, impossible to pedal but prevents death. :lol:
