Park using the waypoint that is listed, or you can try and walk through the small trails that are behind each row of mobile homes and park somewhere near the pond. The Cache is located near the west side of the pond where it turns into a little "stream" looking area on the East end of Cimarron. It is a small-medium container that has been camoflauged.
There is some cool SWAG that is somewhat meaningful to me from my wedding day :-)
