I need to go to Matamoros for business, advice?

So we are setting up temporary operations in Mexico, specifically Matamoros and Tampico.

My plan is to swing and spend about 24 hours, and then leave. I won't be leaving the area around the airport for either city. Will be going with a Mexican business partner, but he is from the south part of Mexico.

Am I going to die? In seriousness, does anyone have any advice, I've looked at the State Department website but it basically says that I shouldn't travel to Matamoros or Tampico at all. That's not really an option for me.
