There were also plenty of crows, of course, but although they are among my favourite birds, I can see them anywhere. There's actually a couple that like to perch outside my livingroom window and preen themselves. It's a sight that I rarely get to see otherwise -- crows are normally so sleek and pristine, but the ones outside that window are all fluffed up with wings splayed while they try to clean out every speck of dust.
This was clearly an area controlled by geeks.
The command is case-sensitive, of course, but given the medium (ie. graffiti) I think that the vandal is allowed some artistic license.
