if I remember right its a good days ride one way maybe 10 hrs one way very doable best place to stay maybe carlsbad?or pecos?me I DO NOT like 285 from carlsbad to fort stockton and pecos a very dangerous road way to much heavy oilfield traffic on a narrow 2 lane tore up road might be a little farther and interstate but consider I25 all way to el paso then to san antonio?
