From what I understand, the border was closed @ 11:30am, so it was a pretty close call. We had heard something was up, so we left a bit earlier than usual to get across before noon.
There was a huge BP presence everywhere, along with fresh & shiny new concertina strung everywhere. The MX fed police were out in force as well on their side.
Closing the border is going to drive the Mexicans insane. So much business is dependent on free flow of US tourists going down, and MX nationals shopping in San Diego.
In fact, we were right next to one of the pedestrian crossings, and it was already backing up. And these were regular Mexican citizens just wanting to cross for the day, so you can imagine how pissed off they are.
As sketchy as the border is, both the US & MX have this weird symbiotic relationship were goods/people actually move back/forth pretty well.
You can image the anger now being directed at the MX gov't for not getting this sh!t under control. It's royally screwing TJ and baja, because now you have all this traffic backed up all over the city as people are freaking out where to stay & hang.
All in all a complete cluster, one which Trump has played masterfully. Just watch the denials of any asylum housing deal in MX be officially acknowledged shortly.
