As it happen in Woodbury Part - I In this section we will try to tell you a little about the evolution of the modern fire engine as it happened in Woodbury. It is important to remember that the evolutionary process takes many years to happen with fire engines.
Money is one of the big factors for the slow pace of evolutionary process.
Fire engines in a large busy city might be replaced every 7-15 years. Whereas fire engines in little towns might not wear out as fast and only get replaced every 20-30 years. The buying of a fire engine is always a large capital expense. Therefore you have to give or take a few years to get the whole picture of the trends in fire engine design in the United States. Some innovations might be just locally accepted.
