Honestly, I bet the old lady ran right into the side of the thing (old ladies are notoriously bad bike riders. *ahem* Grandma -- I saw you hit that bus shelter!). There's a before shot after the jump, but unfortunately the above image has since been removed from Google Maps. I smell conspiracy. I mean, it's not like the old lady asked to have have it removed. Old people using computers -- HA! They're better at avoiding fire trucks!
Hit it for the before shot and a link to the action area.
