I just heard about that yesterday in camp via the grapevine. It sounds like they did that for a few days at the walk in Andrade crossing into Los Algodones. I am not sure where one could go on the internet to see real time news for walking heading into Mexico. They USA Border Authorities post wait times for driving back into the USA but nothing about walking back and also no wait times going into Mexico. That would be from a website from the Mexican government as it is their employees controlling the inspections for driving and walking in. I would have to use a translator to find that link from Mexico authorities.. if there even is one that stays current.
