I have lived in the Philadelphia area all my life, and just recently I have found that there was once a Neshaminy Falls Amusement Park within two miles of my home. In the last 30 years, I have driven by the site thousands of times and seen the wooded area where the park once stood, never realizing what was once there.
Throughout my life, I've learned of a few other parks in the area that are no longer there, but this one being so close to home made me realize I'd like to research these parks of yesterday.
