But you miss so much of the sensory stuff - and beauty - if you don't go out at night! To be fair, a few times a year I catch things like Northern lights: Downtown is just charming with the christmas lights up on the trees with snow on the ground. In autumn the air smells like leaves, and the snow leaves a crisp smell to the air and an oddly echoing silence. Sometimes it downright sparkles from the reflection of the streetlights. Ice isn't so wonderful to walk in unless you've good footwear or some sort of cleats to put on your shoes, but it does give a neat shiny coating to everything, which is especially beautiful during sunrise and sunset - and sometimes under the house lights the trees just glisten with ice.
Walking is my main form of transportation, so I do a great deal of it, and appreciate it so long as it isn't too cold. Granted, I used to view it the same way until I moved here.
