Love riding at night - but always a relaxed pace, at least until I have better lights on the bike. Streetlights are enought to see by most days at a relaxed pace.
I actually figure that between lights and hi-viz orange and scotch-brite, I am probably harder to overlook at night than during the day.
Besides - I ride year round and if I did not ride at night in winter I would not have a lot of riding hours available to me in December and January.
