I commute to and from work, so night riding is unavoidable. I can't say I particularly enjoy it. In England the roads are full of pot holes and grate holes and the darkness makes them very difficult to see. I have to cycle over dark farm roads and country roads and on a foggy night you cannot see a thing! One evening last year it was a real 'pea souper' of a night and whilst I was riding along the farm road, which incidently up hill, so I wasn't moving particularly fast, I suddenly smelt really strong cigarette smoke - and I couldn't make out where the hell it was coming from or who was there!! it really freaked me out, so I can't wait for summer to come and light nights!!!!
