Woodlands, 55 km. I've done this loop so many times, but never at night. The scent of Frangipani flowers fills the night air as I cycle in a car-sparse area. Even the main roads seem bare of cars. It's dinner time, I guess. As I pass the shipyard workmen quarters, the smell of curry wafts through the air. The sun has set, the roads and air have cooled. Same route, different time of day, different experience.
Doing the same thing at a different time can lead to a different result.
