Honk For Clean Air intervention
The sign went up at 2:30am on Thursday morning, May 12. Things went smoothly; eerily smooth really. M dropped E and me off on the shoulder of the freeway. It only took us 2 minutes to attach the sign—even the light of the light post went off once we got started. Then we ran up the embankment and M picked us up. Back onto the freeway to pick up the ladder and we were done.
The sign was displayed for one week in May 2005. Then it was taken down.
