Riding at night is a rythm that's different than riding in the day. Riding at late night on a weekday (read: post 10pm) and things are nice and quiet, at least in Chicago. Less cars and depending on what streets you're on, you've got the city to yourself almost.

I find it relaxing for the most part, and feel like I can concentrate on the ride or my thoughts more than trying to avoid cars and watch for traffic. Taking small streets and alleyways adds another level of stealth and non-disturbance. Night rides are good, that's for sure, decidely different, but good in their own way.
