Speed bumps do a good job slowing down the Fire Department, Police Department, ambulance response, snow plowing and launching kids out of their seats on the school bus.  They also increase maintenace tax dollars. Get rid of them!  The street is not a playground for little Johnny so get your kid/s out of the street and out of the automobile right of way.  The police will do their job enforcing speed limits if you call in consistant problem areas.
