The cache is not a the posted coordinates but a plaque is. You can park within 100 feet of the plaque that is located under a mesquite at the NW corner of the tennis court and pays tribute to the name sake of the Gerald Richey Cross Country Course.
On the plaque there are 24 numercal digits. Starting from top left to right and top to bottom, write these digits down above the letters I've proved below. To make it easier, I've already filled in some of the numbers.
199?2??95?19?8271??71995
