If you find yourself on the interstate going towards El Paso, stop by Hatch NM. It is home to the world famous Hatch chili. Its like breathing pepper spray when you get out of the car. Some great road side vendors selling chili and salsa.

Further south is Mesilla NM. Its old town plaza in Adobe style is a National Historic Landmark.

We lived in El Paso for 2 years recently. There is so much around this area and where you are going first. Makes me want to go back. Have a great trip.
