He's been in the news for several years already. I've looked into doing the bounty hunting thing - I couldn't find anyone in violation! Every truck and bus driver in the city are generally in compliance of the idling limits. Only occasionally would some one-time-visitor out-of-towner who might not be aware of the city ordinance run afoul. Not sure whether people are just respectful of traffic rules, or whether this guy is a menace everyone knows about. If so, the bounty program is working effectively as intended!
