I know this is kinda off topic, but for anyone that is interested in historic parks here is a link to a "dark ride" built in 1905 at a "trolley park" outside of Philadelphia. At the turn of the last century it was one of the top parks in the country and was famous for rides and music. It closed in the 1970s and is now a big shopping mall.

Continuing your off topic post...I grew up a few blocks away from WG park in the 50s and 60 s.
