Tell me about the situation there now.

People who live along the San Ysidro section of the border are always watching carefully. They monitor wait times, they read the news from Mexico, they pay attention to whatever the president is saying. Thousands commute for work and school.

Those commuters are really concerned that the border is going to suddenly become a far less predictable place. Many of them say that San Diego and Tijuana are one region, codependent on each other. If they can’t easily move, it will have a massive impact on the economy and the emotional feel of the place.

There have been fights on this part of the border for decades — in the height of California’s intense battles over illegal immigration, there were often images of people running through the fields in Tijuana at night to enter the U.S.

And of course, there was the infamous freeway sign.

The one depicting the shapes of running people crossing? Yep, I know that one.

Who could forget it?

Are folks worried that this kind of opening and closing of the border will be a new normal?
