The last remains of Lincoln Park with only the skeleton of The Comet still standing.
Well maybe the number of days that it stood isn't exactly 24,178 days but it is a close estimate. I couldn't find the exact date of the Comet standing so I used May 1, 1946 since I know it opened in 1946 (not sure of the exact day).
But, I can tell you that according to www.lpcomet.com/a-little-history that it has been:
24 Years, 9 Months, 1 week, and 4 days since the last ride.
"About The Comet: The Comet was a beautiful wooden coaster (and still is, Standing But Not Operating since 1987). As a matter of fact, there was a roller coaster even before the Comet at Lincoln Park. It was called the “Giant Coaster” and was very exciting for folks in 1914, seeing as coasters were a new thing. Lincoln Park had one of the early coasters in the country. In 1946 this was dismantled and The Comet as we know it was built for $80,000. The coaster was designed by Edward Leis and Vernon Keenan, the latter also designing the famous Flyer Comet at Whalom Park (see our sections ‘About the Comet’, ‘The Comets Family’, and ‘About the Designer’ for more in-depth information). The Comet was constructed by the National Amusement Device Company. The Comet was a pretty big coaster for being in a medium sized park. In the early years volunteers had to act as ballasts and use sandbags to help the cars up and down the hills until the wood was broken in and loosened up so natural gravity could do its work. The Comet was app. 3000 feet and length and gave an incredibly long ride time of 2:10, which is long for a wooden coaster! There were many dips and climbs, giving you that stomach sensation, and made you feel like you were flying! The turns were great and banged you around a bit to give you that classic wooden coaster feel."
