Mexican fire nears half million acres, heading to cities

Mexico is still battling the biggest fire in their history.  The Coahuila fire has burned more than 400,000 acres (180,000 hectares).  It started in mid-March, probably by lighting.

The fires have come within 62 miles (100 kilometers) of the Texas border.  The fires are surrounding the cities of Acuña, Arteaga, Muzquiz, and Ocampo.
