Was back in the area picking up a few drive up caches, on these great roads, that i missed last time and spotted this backdoor entrance into El Corte de Madera Creek Open Space Preserve, which i had no idea was here.
There are many other backdoor entrance's that are marked with a cache, but none with this much available parking, so had to put one here.
Small lock and lock not in the preserve, gps was jumpy at best, clue should help, if needed.
