**The posted coordinates are great for parking and not much else. You'll want to complete the "Ways to ceelebrate 25 years of Geocaching!" Adventure lab to learn the 'almost correct' coordinates.**
25 years is an impressive length of time for geocaching to have been going and it is amazing that there are some players and some geocaches from those early years still active on the game board. There are a lot of ways to celebrate that, thousands in fact, and most of them are legal. This adventure lab celebrates 5 of them.

NOTE: The coordinates you get from the adventure lab are every so slightly off. Every single '3' you find in the coordinates the adventure lab gave you should actually be a 5. Change every 3 into a 5 and you'll be set. You can verify your work with the solution checker.
Best of luck. The park is technically closed at night.
