I suppose I should upgrade my account because part of your chart was covered with an advert for "13 celebs with wickedly weird deformities". I'm not sure why I'm wasting my time on this thread since all that goodness is just a mere click away.

Anyway it's good you're thinking ahead like that but I confess to being fairly light when it comes to planning. It drives my wife nuts. I barely know where I'm going today let alone spend any time thinking about how the upcoming solstice might influence my commute.

In fact this morning I saw my ski goggles in their bag perched upon the shelf where I keep my frequently used outdoor gear. I'm not really frequently using them right now but there they sit.

I do have in my head vague notions of when the equinoxes and solstices are. I also roughly know when daylight savings time begins and ends. Those things matter more in the other half of the year than they do now because of time spent riding in the dark vs light. Weather conditions are really a day to day thing but again this time of year is pretty easy riding compared to Winter so I don't give it much thought.

It's probably not surprising that someone in your part of the world might be more concerned with the Summer solstice that I am. I care a lot more about the Winter solstice when it comes to commuting.
