Yes, Denver had an extensive trolley system that the next generation decided wasn't suited for them and Denver dismantled the entire system and got rid of it.  Then, lo & behold, they forgot we ever had them and thought "wow, what a great system we can have!" and built a new trolley system called lightrail.  See...removing history makes people forget history and they make the same mistakes all over again.  So when we are long gone, let's not get arrogant to say what we are doing now is for the future's good and that the future WILL do as we make them do.
