The last time I entered Kali, which, I will grant, was in 1976, I was driving a Triumph Spitfire, with Illinois plates, and there was barely enough room for an overnight bag. They had me open the trunk, regardless. They seemed somewhat put out that I wasn't smuggling cabbages, or whatever they were hunting for.
They were probably looking for medfly...
some of the inspection checkpoints have been outfitted with license plate scanners and driver cameras...btw last summer I crossed over near parker. There was some unusual slowdown and the CHP seemed to be running the checkpoint. I saw a guy ahead directed to the side. After I passed (with no hassles, just a waveoff) i looked in the r/w mirror and saw CHP running k9 around a truck whilst the driver sat on the ground with his hands behind his head.
