Lately I’ve been riding my 50 yr old British 3-speed “Emma Thompson Bike” around town. It’s been pretty hot and a slow upright bike keeps me from rushing and breaking a sweat.
But she is a bit… well… loud.

When riding a wheel on Sheffield steel folks definitely hear you coming. But the Boston area roads don’t help the situation. They are pretty rough. So I wondered if I could measure the state of the roads by the sounds that Emma Thompson Bike makes? 
You should come to Antwerp…
Beautiful line drawing. Nice spectra overlays!
Beacon St in Somerville was FINALLY REPAVED!! I no longer have to count my teeth after I get home.
