You can't bring a grapefruit across state lines? What is that a reference to?
You cannot bring cherries into california from almost all USA states (except AZ, NV, CO, and WY). I experienced this personally. The state border crossing took cherries from us while we crossed from Oregon, less than 3 months ago, and dumped the cherries in trash.
This is not limited to businesses, and is not a pandemic measure. This has been a long standing policy, meant to protect california's agriculture. Oh, the free trade exponent country has protectionism practiced by its states.
