Thousands of federal, state, local authorities, and even military personnel have flooded this usually quiet community on the banks of the Rio Grande.
Law enforcement patrol in vehicles, on ATV’s, on bicycles even on horseback.
Helicopters monitor from above, while high powered air boats prowl the shallow water of the rio grande.
The security surge is in response to the arrival of a caravan of 1,800 Central American migrants just on the other side of the border said to have their sights on seeking U.S. Asylum.
So far authorities say no caravan members have crossed illegally into the U.S.
Local leaders credit not just the American show of force, but also a new stepped-up effort by the Mexican government, using its military and national police to keep caravan members under control.
But processing 1,800 asylum seekers will take months.
Officials say about 16 to 20 asylum cases can be processed each day.
Meanwhile, the migrants are staying in an old warehouse that has been turned into a shelter.
