And neither was this bridge. It seemed to take forever. But they did a pretty decent job.
First of all: DON'T DROP IT!!!
This geocache is along the bike and walking path connecting Solana Beach and Cardiff (you know....by the sea). It is NOT accessible directly from the Interstate Highway known as "Five" but it is accessible if you exit the freeway to take in the view at the Vista Point at the accompanying coordinates. Since it isn't ON the freeway, and we can reveal that it isn't ABOVE the freeway, that leaves just one other place to look.
As a reminder: DON'T DROP IT!!!
The coordinates here may be a bit inconsistent so here's some additional information that may help. Go to the ocean side of the walkway (not ON the freeway). Find the 8th cable stay. Look down and just to the right of that cable. You hopefully will see a nano there.
Finally: DON'T DROP IT!!!
