Asked wifeanon about the facebook page where the caravan is supposedly headed to Reynosa, but she couldn't remember where she saw it, just someone posting.

But, to get some sort of update on the caravan location, Univision has a Diary Blog that they are updating regularly.

Looks like they spent Monday night in a park, church, and basketball courts in Huixtla, Chiapas.

Los migrantes durmieron la noche del lunes a ras de suelo en un parque, la iglesia y la cancha de básquetbol de Huixtla, en Chiapas, un estado fronterizo con Guatemala.
