Noodling around backroads is a favorite hobby of mine, particularly on the sunny warm evenings after work when Highway 1 is jam packed for the daily 5 mile Authomotive Conga-Line through Moss Landing. I liked this road as there's some places to pull out and not a lot of houses around to fret over muggles watching as you search. Or hide, for that matter.
Cache is not on the fence or posts or gate, so don't look there.
