On that day, walk is the perfect thing to do.

I was living in Seattle in 1998-99. We had something like 145 days of cloudy weather in a row. Mt. Baker Ski area had over 1,100 inches of snowfall that winter. I was outside walking every single day. Or snowshoeing, x-c skiing or something.

And I did not notice the gloomy grey weather. It was only when the sun came out and I heard other people talk about dark it had been that I realized what just happened.
