California does not have the interstate inspections anymore. Last time I drove back from Reno on I-80 the booths for the inspection were gone.It's not quite pointless. If you're stopping people anyway at the border anyway, why not do an agricultural inspection? Even if you only slow the spread of pests, or reduce their rate of introduction, that is some accomplishment, since they travel much more slowly on their own.Its one of these things that looks impressive and makes like the government is doing something, but is fairly futile when there is a 5000 odd mile long border for those nasty fruit flies to sneak across.Has nothing to do with national security. Has everything to do with spreading insects and disease.How could raspberries (and other fruit) threaten national security?
You can understand it for overseas travellers, but for travellers on the same continent it's quite pointless.
I'm not sure how useful interstate inspections are, like what California does, but its borders are pretty hostile to invasive species.
There's a great article in last week's "New Yorker" on invasive species in Florida, including a great description of a death match between a 6-foot alligator and a giant Burmese python.
I always thought the California inspections were useless because the booths were after the first exit within the state. You could just as easily get off at the first exit and bypass them.
