This cache is at the beautiful and historically significant La Raza Park (formerly known as Columbus Park). In the middle you will find a gorgeous structure known as a "kiosko". But that's not where you'll find the cache.
This cache is hidden on the West side of the park. When seen from the sky, there is a trapezoid shape to the sidewalks which encompass the cache's location. Near the middle of that trapezoid is a green, man-made structure. That's your target.
This cache is very small (fingertip sized), and magnetic. It is camouflage colored, so look extra carefully. Bring a pen and tweezers.
