The caption in the photograph, "Speed bumps are to blame for the melting of the ice caps," is FAR too strong. However, they do make a point, there, but...they seem to be dissappearing in my area.
yeah, speed bumps are rare as hen's teeth around here, mostly in store parking lots, but they're even dissappearing from THERE. I can only think of one public highway that has (intentional) speed humps, and that's Prospect Drive in Peoria. They're nuisances to most.
Coming up to another intersection, they used to have "Wake Up" buzzer strips across the road, but these were removed with a repaving. It seems traffic control devices just aren't getting replaced around here.
