Black Hole
I grew up in SF. Lived practically all my life here. I can say I know the city in and out...except for one area. That's the woodsy area by Glen Park. This is the one "black hole" in my knowledge of this wonderful city. Everytime I drive by on O'Shaughnessy Boulevard I look over to the canyon and wonder what's there. This green and woodsy patch seem so far removed from the metropolis city, but yet, it's smack in the middle of the city. I've always wanted to wander into this black hole and explore. Today there's an article on SFGate.com featuring this rare jewel of the city. It offers information on how to get to the area, how to navigate the canyon, and even where to stop and eat afterwards. Armed with this information, I'm determined to finally pay this gap in my geographical knowledge of SF a visit.
