There is an Adventure Lab cache series that starts very close to the posted coordinates. Adventure Labs are virtual geocaches that require an application on your mobile device. The Adventure Lab at this location is called Waco Sculpture Zoo. If you find the Adventure Lab caches, one of the stages will provide you with the coordinates for this bonus cache! The posted coordinates are a good parking spot for both the lab caches and this physical cache. See https://newsroom.geocaching.com/adventure-lab
