Perhaps you haven't had the pleasure of eating fresh-picked strawberries from Watsonville on your drive down PCH 1. Strawberries that are shipped across the US (Watsonville produces something like 40%) are picked under-ripe and will not sweeten more along the way.

Ripe, Watsonville farm-stand strawberries are something else entirely. They can indeed be fist sized. I encourage you to try them yourself.

Alternatively, you can go to pick your own places along the way - also fantastic.

There used to be an amazing upick organic strawberry farm just past La Selva. I saw exactly what they put in them. Eating huge strawberries perfectly ripe, picked a half hour ago from there was incredible.

I've had a similar experience when shopping at a gas station store that bought produce from a local strawberry patch. Unfortunately, it was on a road trip.

They are in Japan.
