Today as I was heading out of the Fine Arts building for lunch I saw an interesting sight:

These people were participating in Park(ing) Day here in San Francisco.
Trust for Public Land, the organizers of the
event, describe it like this:
"PARK(ing) Day is a one-day, global event centered in San Francisco where artists, activists, and citizens collaborate to temporarily transform metered parking spots into 'PARK(ing)' spaces: temporary public parks."
I must say I think it's brilliant. I wished I could skip class to feed the meter all day. Sometimes we need a little patch of personal green in the middle of the concrete jungle.
