The organ at Wanamaker Building in Philadelphia. The organist is playing an English Christmas Carol “I Saw Three Ships.” This is the King of the King of Instruments - the largest fully functioning pipe organ in the world with 28,750 pipes. Right here at 13th and Market! Crazy!

@tweetlikemaya Some crazy zoning or construction code. Some code says you can not obstruct views with a fence but there is no corresponding code for gates. So you end up with stuff that makes no sense except to L&I inspectors.
