A bike lane inventory: audio edition

These are the sounds I heard today in the bike lane:

• Wind.
• Wind chimes.
• A construction worker singing "Cat's in the Cradle" at the top of his lungs.
• Birds singing at the tops of their lungs (song unknown).
  
• Engine noise as cars rapidly accelerated from stop signs at one side of the block. Brake noise as cars rapidly decelerated for stops signs at the other end of the same block.
• The whine of a circular saw.
  
• The click of my bike's freewheel.
