The coordinates will take you to an information sign and disc return station near the "back" parking area for Kelley Park and the San Jose History Museaum. At this point also kind of in the middle of the disc golf course, but the area is not usually very crowded. The cache is a micro hidden in a slightly evil manner, but shouldn't be too hard.
Please search only during park hours of 8am to 1/2 hour after sunset.
