Debris, hazard free bike lanes are essential keys to usability of bike lanes. Exactly how well city officials and employees understand this is something I wonder about. Of the range of debris that can be a hazard to use of bikes in the bike lane, I particularly wonder to what extent they're aware of the small end of that range that pose a hazard to bike travel.

Bits of glass that can cause flats can be very small...much smaller than fingernails. Often it's possible to see glass on the bike path due to the light reflecting off of even tiny bits of glass. The fact it's there though, leaves the bike path where such glass is present, barely usable. Glass on the bike lane, obliges people to ride the main lanes.
