winter cyclists - what is the hurdle?

[Becky]

Darkness isn't really an issue in Belgium... every street has streetlights...

You are very fortunate indeed. Some of the darkest sections of my commute are the most urban sections, where the city can't be bothered (or can't afford) to fix the broken streetlights.

Then there's the problem of my glasses fogging up; haven't really figured that one out yet.

I've had reasonably good luck with a lens-cleaning product called "Cat Crap". It seems to help with the fogging, although I still pull my glasses away from my face at traffic lights to avoid excessive fogging.
