Mexican customs to phase out traffic light lottery

We got the red light, after crossing at Laredo, when driving down in '96... with a van. Musta been a slow day for them 'cuz there was not a single solitary other vehicle around. They wanted us to unpack the whole van in the heat of the last week of April. I asked what they were looking for because every single thing was personal for our own use. They musta seen the look of indignation on my face and relented. I was hot, sweaty and frustrated... also didn't speak a word of Spanish except for please and thank you.
So the stop is there Mike, about a half an hour in from the border, you just missed it.
