very early in the morning, just before or just as the sun is rising - NOTHING moves, except birds and other animals, everything is totally quiet, and the light slowly gets brighter and brighter...so awesome. particularly if it's an early sunrise, like 4-5am, so no-one is awake at all. I don't smoke at this time often, but I love it when I do. if you can get a good view of the sunrise, even better.
