Hello Cachemas FTF hounds...did this divert your attention slightly?
In any case this is just an easy projection cache from the posted coordinates,
which is also a good place to park.
Project due east for a distance of the length of a standard tennis court X 4.
Happy Hunting at Heman 
.
Heman is the largest park in University City and has amenities for sports enthusiasts, picnickers, families, and community groups. Now it has more amenities for geocachers as well. Heman Park is open from 6 am to 1030 pm daily, so if you come after dark you may need a flashlight. Permission to place was granted by the University City Parks and Recreation office.
