If you're talking about riding, you can leave El Paso via Sunland Park and Santa Teresa (NM) getting on Hwy 9 across the southern border, through Columbus to Hachita then South on 81 to Antelope Wells. This path is at least 25 miles shorter than going across I-10 then south to Hachita and Antelope Wells.
Hwy 9 is paved nicely, not too much traffic. Traffic is mostly cross traffic from Mexico, plus there are plenty of Border Patrol types. There are no stores after Santa Teresa until Columbus. Then nothing again on down to Antelope Wells and back up to Separ. There are intermittent reports of water at Hachita, depending on who you find at home.
Anywhere down that way there's potential to encounter smugglers of illegals or drugs. That's not limited to Hwy 9 and includes Hwy 81 to Antelope Wells.
