Once the 8 turns into the 10, she’ll go through a few large and a few smaller size cities. It might be a good idea to MapQuest out the mileage between these:
Tucson, Arizona
Lordsburg, New Mexico
Deming, New Mexico
Las Cruces, New Mexico
El Paso, Texas
Van Horn, Texas
San Antonio, Texas
Don’t go all the way to San Antone, turn east on U.S. 290 once you are south of Junction.
printing and mapping now...thanks for the tips
