Traffic congestion on LSD: it's the trucks' fault

Stuck in traffic on northbound Lake Shore Drive last Friday, I kept looking for an open lane that may have been moving faster. I was struck (not literally, thank G-d) by the surprising number of trucks on the Drive. The City bans trucks from the Drive, except to access McCormick Place. I fell behind one pickup truck with Florida tags that may have missed the "no trucks" sign. There were at least two others. If I had been driving a police squad car, I would have had numerous easy tickets despite the heavy traffic (no speeders). Until it decides to repeal this law, the City should make an effort to enforce it by ticketing trucks on the Drive.
