When I worked in Tijuana I stayed in San Diego and each morning I would drive to the border crossing and park my car, walk across the border (I had a work permit) and meet my driver who would take me to the factory were I was working. At the end of the day the trip simply reversed. The only time that I left the fenced and walled factory for lunch was with a group of my associates (all Mexican) with me.
