Nowadays, in Boulder, many lights have either CCD cams or speed
sensors. The CCDs photo ID people running the red, and the speed
sensors actually trip the green to red if the cars approaching
are going too fast. In betweenst, we have photo radar units
in unmarked vans sitting around here and there. [geez, I read
about places like this in books when I was growing up].
