"Pretty much anywhere other than SF can have fresher food." Says nothing about being limited to the 7 states with more farms than California (to say nothing of the different crops that are grown on these farms: Iowa grows almost entirely corn and grains, so your fresh produce is going to be limited, or you'll be getting things from smaller boutique farms, which you'll find in all states and so produce depends mostly on climate).

> you’ll be getting things from smaller boutique farms

Bingo!!
