Tomorrow, at 19:21EDT (that's 7:21pm eastern daylight time), the sun crosses the equator on its annual track north. In simplest terms, that means spring arrives and the winter of '10-'11 comes to a close. That doesn't mean it won't snow but it does mean that, after tomorrow, the days will be longer than the nights until the first day of autumn.
Mostly, though, it means we are one day closer to being able to get our trikes out of storage and back onto the road. I've already switched to wearing my trusty running shoes. The sidewalks are mostly devoid of icy slush, replaced, however with gravel, larger salt cubes and other detritus. The snowpack is much reduced in a lot of places with open areas revealing the brown and flattened grasses from last year's warmth. The sun sits noticeably higher and its power continues to reduce the icy snows into a hardened dark grey mass. Tiny streams form and trickle under these mostly hardened plates of icy chill running down sidewalk cracks, curbs and flow more or less evenly into drains.
I am very attuned to the seasons themselves but mostly during those precious few weeks when the seasons shift.
