Not me biking this time, but:

Lady: (crosses Northern Lights on her bike going north at the C Street intersection. Stops briefly at the NW corner to wait for the perpendicular crosswalk)
Josh: (driving, southbound on C Street, windows down, singing at the top of my lungs) "...You're a heart-shaped box of springs and wire / You're one badass fucking fractal!"

Didn't realize what that might have sounded like until about a minute later.
