We decided to break at Grants, NM staying at a Passport America park right off the interstate. We might have thought that the interstate noise would bad, but I never heard any road noise because of the sounds of the trains! Evidently this was a major train intersection and they ALL had to blow their horns long and loud. This continued all night. Had we not already paid for two nights, we would have left.
We spent a lot of down time reading etc. We did get to a super walmart and watched a lot of movies.
