Thanks for the information.

The folks who answer the phone - quite nice - have never received a call about bicycles. They referred me to an engineer - also quite nice - who relates that Denver adjusts loops in bike lanes but nowhere else. Perhaps Stuart can do better.

I know you meant this well, but this is not someone I would call. He is an oldtimer at the city. He probably also means well. Nonetheless, the new lights installed at Stapleton just this year still malfunction (and a significant number of Denver's bike routes use sidewalks.)
