I'm sorry it's been so nice in SF that the roads are too cluttered. ;-) Beantown is wetter and colder right now with reduced ridership, and fewer scofflaws. :-)

I only run lights at locations where there is never cross-traffic, and where a light should not have been installed in the first place (in my opinion). When I do run a light, I'm sure to check for cross-traffic, pedestrians and Coppers first.

There is a special place in Hell for cyclists who run cross-walks with pedestrians in them.
