You're looking for a camo'd pill bottle a few feet from the trail.
If mountain roads aren't your thing, you might want to skip this one. But if you love them like I do, come on up, enjoy the view, and grab a cache (or a bunch of caches if you feel like hitting the trails.) El Sereno OSP is open half an hour before sunrise to half an hour after sunset. Happy hunting!
Congrats to PAVEIT on the FTF!
