Passage
You may have noticed that 12 new stoplights were added to the streets of
Darlingham in the last year. Though there have been many complaints about
slower commutes to work that is a small price to pay for the dramatic
improvement in community safety that has occurred. In fact, as a result of the
new stoplights, automobile accidents at those intersections have been
reduced by nearly 40 percent. Furthermore, studies show that the new lights
have made the intersections safer for pedestrians. And for me personally, the
stoplights hold a special significance -- they were manufactured at Wilson
Smelting, the company my grandfather started almost 80 years ago. In
closing, I think we as a community should thank the city planners for making
the safety of Darlingham's citizens a top priority
