The agricultural inspectors at the borders never cease to surprise visitors from out-of-state. It can be quite amusing.
But why would they have no controls at either entry point from NV to South Lake Tahoe, but have a stop at the much more sparsely used US 395?
Because they don't want to inconvenience the folks who drive from South Lake Tahoe to Nevada to gamble or go to work every day, and a rogue sandwich isn't going to harm the minimal agriculture in the Lake Tahoe area. Fruit flies could just fly the short distance from Nevada, anyway.
The agricultural inspection area on US-50
appears to be in the town of Meyers, just before the US-50/CA-89 split, about 10 miles from the state line.
These things remind me of the outfield US Border posts miles away from the US-Mexican or Canadian border. I can only imagine the spooked tourists who don't live in the border states panicking that they've somehow inadvertently driven into Mexico the first time they encounter one.
