Reynosa, Mexico
Situated just across the border from McAllen, TX, Reynosa is a major port of entry on the northern border of Mexico. It’s especially popular with Texas residents who frequently cross the border in search of cheap prescription medicine, dental care, and shopping. The city is largely under the control of the cartels, though. While they have a strong interest in keeping the city safe and often police it well, conflicts between rival cartels can cause serious problems in Reynosa.
