There are legitimate enforcement zones where I welcome the speed cops, places where speeding is stupid and dangerous -- like my congested residential neighborhood with its elementary schools, retirement home and kiddie playgrounds. Ticket away, officers, with my blessing.
Then there are actual speed traps, in locations chosen to raise ticket revenues and fill quotas. These are usually set up where there's a good place to hide the cruiser with a view of a safe, wide-open road where drivers are likely to break the artificially low speed limit. They have nothing to do with safety.
