Swing, Swing...

No, I am not referencing that All-American Rejects song, although I will admit that I was a closet fan of theirs back in the day, I digress....So, how cool is this set of pictures of a swing being installed on a BART train in San Francisco?! I wish someone would do this on the trains here in Chicago. Of course they'd have to install them at night and remove them in the morning during rush hour when you're stading so close to people you can practically guess what they had for breakfast.

WEEEEEEE!!!!
