Have you taken the Broadway tunnel sans critical mass lately? There are new TREES!
I was taken back and did a double-take while questioning my caffeinne intake, because those trees were looking rather strange. Then I realized the wind was tremendous, but it wasn't that. There were about a dozen of these natural creatures attempting to clean some of that thick air in there. Nice, I like it. They look tilted as they were mid-process of being planted.
There are many changes around the city, the Divis corridor, Valencia street, market street, very good things happening. I hope one day I get to ride the Geary tunnel alongside moving traffic, but don;t really need to so it's all good. Often time I ride both tunnels at once (Broadway +Stockton) and it is actually one of my favorite things to do occasionally, late in the evenings. The noise can be a bitch, but somehow I find it very beautiful, especially around 9 or 10PM when the lights are on, the ugly as hell yellow mosaics somehow look nicer, the dirt and filth dust on the walls begins to form ghostly shapes, all the Muni express lines are long gone, and Chinatown ceases chaotic activities.
Random weeknights are a critical mass of one.
