Alert to Grey Line: New Attraction in the Mission

While it's clear that there are three top tourist attractions in San Francisco: Golden Gate Bridge, the Giant Sundial and Alfie's Troll Altar, I have lately noticed one that might be number four on the list. Though the displays lack Alfie's Vegas extravaganza panache, the apartment building at the northwest corner of 21st and South Van Ness has got some pretty groovy stuff going on.

Check the unit on the third floor, west end and look up. Not sure what all is up there, but it looks pretty dern good.
