NASCAR heads back to the United States after a trip to Mexico City. The first Mexico race may not be the last. Autódromo Hermanos Rodríguez hosted Xfinity Series and Cup Series events over the weekend.

It's expected to be 74 degrees with a 21% chance of rain at the start of the Xfinity race.

Logistics a factor, and a decision about any NASCAR return to Autodromo Hermanos Rodriquez next year is expected to be made in the next month or two.
