There was a time in this country when, in almost any city, you could ride a trolley.

In the early 1900s trolley companies operated over 17,000 miles of track.

These companies started buying land at the end of the line - adding picnic areas and playgrounds.

These trolley parks helped usher in the golden age of amusement parks.

Once there were over a thousand trolley parks.

Now only a dozen remain.
