Dear Commissioners:
I have enjoyed for many years the privilege of living in one of the safest neighborhoods in the country. Today, a large majority of this community feels that our security is compromised by a serious threat. You alone can help us to remove this danger from our lives. There have been a number of serious accidents at the crossroads and crossings along Main Street due to increased traffic through our town. We beg you to place effective streetlamps along all the crossroads and crossings as soon as possible. By doing this, you will save many lives and earn our gratitude.
Sincerely,
Debbie Green
