Not only that, there are several roads that don't even have check points if you wish to enter CA from any state.
All said, the California Inspection stations are a joke. We came back into California recently from Las Vegas. The Ag Inspection Station straddles I 15 just east of Barstow ( more than 150 miles inslde the state). We wondered, on a Sunday afternoon, why the freeway was stopped just outside Baker. It took two hours to reach the “accident,” the Ag Inspection station. The funny thing was we saw an 18 wheeler leave the freeway at Baker and proceed on the frontage road, as were all the folks in the know. At the Ag Inspection station you could see the congo line on the frontage road bypassing the check point. But at the end, they weren’t inspecting anything, you just had to slow down to a crawl so the moron in the dayglo vest could inquire as to where you’ve been! The person indeed looked brain dead, just a gov’t automaton putting in his time. I’m all for keeping California agriculture pest free, but these stations aren’t doing the job, they’re just a major inconvenience.
